How to earn Bitcoin?

Overview - Table of Contents Introduction to Earning in Bitcoin Work for Bitcoin Sell for Bitcoin Affiliate Programs Gambling Bitcoin Mining Hardware Mining Cloud Mining Introduction to Earning in Bitcoin Bitcoin is the most popular digital currency in the world today. Bitcoin cloud mining is the fastest way to immediately begin earning bitcoins. Bitcoin is built using very complicated cryptographic principles, and supported by countless individuals and companies from all around the world. By early 2016, total Bitcoin market capitalization had crossed USD 7 Billion, making it almost as valuable as the GDP of a small country like Bahamas. All the other digital currencies together do not constitute even 20% of Bitcoin’s market capitalization, underlining the its dominance and importance in the world of digital currencies.
With such a huge amount of world’s capital available in the form of Bitcoins, the number and types of opportunities to earn in bitcoins are increasing by the day. In this article we will discuss such opportunities that help us earn bitcoins.
We will start with the easiest, or the one that is applicable for the maximum number of people, and then move to the tougher ones. In the end we will cover earning bitcoins by mining. Bitcoin mining is not an easy way to earn bitcoins, but we do have a number of easier ones we will discuss first. So lets start with ‘earning bitcoins by offering your services’
Work for Bitcoin Perhaps the easiest way to earn bitcoins is to work online or in real life for bitcoins. Because of the huge size of the bitcoin eco-system, a number of such opportunities and jobs are available. With Billions of dollars invested in Bitcoin by tens of thousands of people, there is a real market in Bitcoin, where you can find jobs for freelancers, software developers, writers, and others who get paid in bitcoins for their services.
Software development, writing, design, making websites or apps, audio transcription, are some of the most active types of jobs. You can easily discover the types of jobs by going over the more popular job boards for bitcoin related work. The following job boards or forums are some of the best places to look for such jobs or gigs.

Sell for bitcoin You can also get Bitcoin by selling your old laptops, phones or other items for Bitcoins. Such types of transactions are happening more and more, and a lot of buyers are already buying anything from iPhones to even cars by paying with Bitcoins. For Americans, Craigslist.com is your best bet when you want to find such buyers. You can mention in your ad that you are willing to take payment in Bitcoin. This way if anyone wants to buy the item for you for Bitcoin, they can contact you and make an offer. The same principle applies to other online marketplaces such as gumtree for UK, kijiji for canda etc.
Affiliate Programs Affiliate programs allow a promoter of a business or product to earn money or bitcoins by refering new clients to such businesses or products. For example, amazon.com has a popular affiliate program, where you can earn commission ranging from 2% to 20% for refering clients to products listed on amazon.com. Amazon normally pays in dollars, but there are a number of other sites and businesses which pay you in bitcoin for acting as their affiliate.
Some of the more popular affiliate programs that pay out in Bitcoin are by the sites: cex.io, coinbase.com, okcoin.com and namecheap.com, among others. You can find a larger list of such affiliate programs on the bitcoin wiki page for Affiliates.
Gambling We do not recommend gambling for every player or every user; we find that gambling is only suitable for people who know how to win at it. However, if you are one of such lucky users who have some tricks up their sleeves, and can manage to win at games such as poker, then you will find that earning bitcoins is not that hard.
One of the many applications of bitcoin since the very beginning have been in betting games or gambling. Because of the relative anonymity of bitcoin, and the lower fees, it is very suitable for gambling related applications. Indeed, one such game, satoshiDICE, has been running since 2012, and has paid out a huge number of bitcoins in innumerable transactions to its winners. There are many such games, which you can find be googling.
If you want to gamble totally anonymously, you can play gambling or betting games that are available only on darknet or .onion sites. Such sites allow you to browse them anonymous by operating on the tor network, which is a secure network that allows users to browse .onion websites without exposing their own IP address.
Bitcoin Mining For each block that is added to the Bitcoin Blockchain, a number of bitcoins are rewarded to the creater of that block. This reward is currently, as of June 2016, 25 bitcoins per block, and it halves every four years. The next halving will be in July 2016. Creating or finding the new blocks, and therefore winning the reward of 25 bitcoins for each block you create, is called bitcoin mining. To do bitcoin mining successfully, you need very powerful computers, which compete with other computers to find the next block. The speed or power of computer that do bitcoin mining is calculated in hashes calculated per second.
There are two ways to do bitcoin mining: one is to own hardware or computers that do the mining, and second is to hire the hardware from a third party, usually online, and do the mining on the cloud. Let us discuss the advantages and disadvantages of both in next two sections.
Hardware Mining When you own the hardware that does the calculations and mining of bitcoins, its called hardware mining. Hardware mining is the more popular or prevalent of the two types of mining we mentioned. One of the biggest factors which comes into play when doing bitcoin mining using your own hardware is the price of electricity. If you pay top price for electricity, then bitcoin mining may not be your cup of tea. Another related factor is infrastructure needed to cool the hardware; since every cpu generates some amount of heat, you may need to cool the hardware in case they become too heated. No wonder that some of the most successful miners work from China, specially Tibet, where they can get cheap electricity, and their cooling costs are low due to high altitude which reduces the ambient temperature for them.
For a more in-depth information on how to setup your hardware mining equipment, have a look at the Antminer setup page.
Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are:
AntMiner S7 AntMiner S7 Bitcoin Miner 4.73 Th/s 0.25 W/Gh 8.8 pounds Yes $479.95 AntMiner S7 Bitcoin Miner 0.1645
AntMiner S9 AntMiner S9 Bitcoin Miner 13.5 Th/s 0.098 W/Gh 8.1 pounds Yes $1,987.95 AntMiner S9 Bitcoin Miner 0.3603
Avalon6 Avalon6 Bitcoin Miner 3.5 Th/s 0.29 W/Gh 9.5 pounds No $499.95 Avalon6 Bitcoin Miner 0.1232 Cloud Mining There are a number of service providers that allow you to rent computational hardware from them, which can then be used to do bitcon mining. Some of these services are designed with bitcoin mining in mind, whereas others such as Amazon AWS are general purpose services that can also be used to do bitcoin mining.
Some of the cloud mining services which can be used to do bitcoin mining on the cloud are:
Hashflare Review: Hashflare offers SHA-256 mining contracts and more profitable SHA-256 coins can be mined while automatic payouts are still in BTC. Customers must purchase at least 10 GH/s.
Genesis Mining Review: Genesis Mining is the largest Bitcoin and scrypt cloud mining provider. Genesis Mining offers three Bitcoin cloud mining plans that are reasonably priced. Zcash mining contracts are also available.
Hashing 24 Review: Hashing24 has been involved with Bitcoin mining since 2012. They have facilities in Iceland and Georgia. They use modern ASIC chips from BitFury deliver the maximum performance and efficiency possible.
Minex Review: Minex is an innovative aggregator of blockchain projects presented in an economic simulation game format. Users purchase Cloudpacks which can then be used to build an index from pre-picked sets of cloud mining farms, lotteries, casinos, real-world markets and much more.
Minergate Review: Offers both pool and merged mining and cloud mining services for Bitcoin.
Hashnest Review: Hashnest is operated by Bitmain, the producer of the Antminer line of Bitcoin miners. HashNest currently has over 600 Antminer S7s for rent. You can view the most up-to-date pricing and availability on Hashnest's website. At the time of writing one Antminer S7's hash rate can be rented for $1,200.
Bitcoin Cloud Mining Review: Currently all Bitcoin Cloud Mining contracts are sold out.
NiceHash Review: NiceHash is unique in that it uses an orderbook to match mining contract buyers and sellers. Check its website for up-to-date prices.
Eobot Review: Start cloud mining Bitcoin with as little as $10. Eobot claims customers can break even in 14 months.
MineOnCloud Review: MineOnCloud currently has about 35 TH/s of mining equipment for rent in the cloud. Some miners available for rent include AntMiner S4s and S5s.

[Informational] [CC0] Bitcoin Off The Chain

Off-Chain Transactions

The goal of Bitcoin is to serve as a world currency. Although Bitcoin is often associated with the Bitcoin Blockchain and the Bitcoin Peer to Peer network, Bitcoin is also an abstract concept of value that can be used without either of those things, merely to represent debts or credits on any arbitrary ledger. Using Bitcoin for its abstract value characteristics is called using Bitcoin as a unit of account. Transactions on ledgers other than the Blockchain ledger are called off-chain transactions.
Transactions outside of the Blockchain obviously lose all of the benefits of the Blockchain, but they are also not subject to any of the limitations of the Blockchain. The most commonly lamented limitations of the Blockchain are its limited speed, its inability to reverse fraudulent transfers, its limited capacity and consequent high expense, its limited privacy, its technical complexity, and its limited micropayment support. Since off-chain payments have none of the restrictions of the Blockchain, they have an opportunity to address those limitations.

Custodial Transactions

The entire world's economy already runs on digital transactions. The world uses a wide variety of systems to accomplish this goal, but almost universally the systems used are abstracted from the core unit of value being transferred. A financial transfer system that moves U.S. dollars like PayPal is not very different from a financial transfer system that moves Chinese Yuan like AliPay. Using a Bitcoin unit in the place of a fiat currency unit in these existing systems would be easily possible, although the negative impacts of departing from the trust-minimizing and durable Blockchain are not to be discounted.
Even since the early days of Bitcoin, transactions using custodial proxy systems have comprised a great majority of the exchanges between Bitcoin users. There is then ample evidence of the perils and promises of such systems. A common example is the Mt. Gox exchange, which offered an innovative rapid fund transfer system for exchanging Bitcoin, at the cost of requiring counter-party trust in the system. As is well known, the counter-party trust in the system would come to be misplaced, but the general innovation held: after Mt. Gox, the vast majority of Bitcoin exchanging and most likely trading of any kind came to take place through proxied off-chain ledgers.
To improve upon the problematic Mt. Gox model in which complete trust was a near absolute requirement, two solutions have been devised. The first is a layered security approach in which redundant trust systems are used. This is represented through multi-signature control of funds, which requires two independent parties to sign-off on fund transfers, to prevent unauthorized movements of funds. Exchanges and companies have sprung up to use this model, as it reduces the risk to all parties, a risk made all too apparent by the dramatic failure of Mt. Gox.
The second security solution is to use a combined signature scheme to prove to users that their funds are still present. The exchange simply cryptographically signs a public statement that user funds exist, by signing a known state of the overall system based on a collective signature of every users' funds. The exchange then allows users to spot check their own funds and compare notes to prove that the exchange cannot be playing games with the numbers by showing the same funds to multiple people.

Blockchain Proximate Transactions

The spiritual ideological foundations of Bitcoin are those of the crypto-anarchist movement, which promote the value of encryption and efficient information transfer and attempt to avoid trusted systems. From this perspective, even strong trust mitigating tactics may be seen as imperfect or insufficient if a small number of trusted custodians are necessary.
With the goal of avoiding trusted custodians in mind, off-chain applications are still possible through two potential methods. The first method would create new similar structures to the Blockchain ledger, with a set of distributed judges who would determine the state of the network. These judges might be in an open competition for fees, as they are in Bitcoin, or a large set of trusted individuals or companies, or even the Bitcoin miners themselves.
These ledgers would then synchronize with the main ledger using a series of swaps, which would lock coins on one side and free coins on the other side, giving a one to one exchange rate. This idea is known as a pegged sidechain, and it would allow for a completely different rule set on the other ledger, while maintaining the value peg to Bitcoin in a trust-minimizing way. A major issue with this proposal is that the sidechain judges would still have to have trust invested in them to not end their cooperation and attempt to unlock funds from the sidechain using a forged history.
The second more secure proposal for trading Bitcoin off-chain is through the use of signed but not published Bitcoin transactions. This concept uses transaction multiple signature fund locking and timeout features to create funds that are invested in a relationship between two users, who may then update the state of their relationship out of band with the Blockchain.
If there is a cooperation failure, neither side may claim funds on the Blockchain that are not theirs because they are missing the appropriate signature and they are also protected by a resetting timeout function that restores funds after a period in which the relationship is proved to be non cooperative. This proposal is called payment channels and exists in the form of libraries such as 21 computer and BitcoinJ, and in the form of services such as 21 market services and the streamium.io video streaming service. This is also the foundational concept used by the Lightning Network proposal, which is essentially a network of payment channels.

Bitcoin Backed Currency

As Bitcoin was modeled upon gold, it may be used just as gold and silver were used to back currency in a model that served the world economy for much of human history and is still a highly regarded option in many circles. In this model, existing currencies would simply switch the meaning of their existing notes to peg their currency to a Bitcoin amount.
This peg could be accomplished by the governments in question purchasing large sums of Bitcoin to hold in reserves, allowing for exchange at a fixed and published rate. This could be done even in part, with a country holding a basket of assets that would install confidence in a currency not being adjustable at the whims of a voting public or a ruling sovereign.
In this system, every exchange of paper notes or bank transfers could be thought of as an off-chain exchange of Bitcoin. A crisis in confidence in the note would be immediately obvious in non-official market prices. As an improvement over gold and silver backed currencies whose assets are frequently called into question, Bitcoin could allow for mathematical certainty as to asset accounting accuracy.

[Informational] [CC0] Smart Money

Smart Contracts

Bitcoins on the Blockchain are moved through transactions, which are simply files that contain cryptographically signed statements about the movements of coins. The entire Blockchain history is basically just a giant set of these signed statements, Blockchain balances are always determined by following the chains of ownership declared by the transactions.
The signed statements in transactions can actually be thought of as a signed contract: a buyer signs an agreement to send an amount of Bitcoin to a seller. The language of a transaction is a flexible language, like a computer scripting language. It can express a wide variety of statements beyond the simple statement of "send funds to address". Because there is this variety of expression, Bitcoin transactions are sometimes also referred to as smart contracts.

History of Smart Contracts

In the original envisioning of Bitcoin, many types of transactions were envisioned: Satoshi Nakamoto carefully thought out a set of language primitives that would allow the expression of a wide variety of smart contracts. Due to the complexity of crafting easy-to-use tools to form these contracts, the Bitcoin client left their construction as an exercise to the future developer.
Satoshi's decision to design a system that allowed complex contract formations was quite controversial. Gavin Andresen and Jeff Garzik lobbied strenuously for a simplified system, with Jeff Garzik going so far as to demand repeatedly that all smart contracts be removed from the system. Luke-Jr, Greg Maxwell, Theymos and others argued against this restriction, looking towards the future promise of smart contracts to power advanced Bitcoin applications.
When Satoshi published Bitcoin version 0.3.18, he created a rough compromise, based on Gavin's suggestion: create a standardized rubric for what transactions look like and refuse to allow unknown constructions to be shown to users or relayed on the network, in an opt-in whitelisting system known as standard transactions.
Over time as Jeff Garzik and Gavin Andresen's influence waned and their fears were proven unfounded, the limitations of the whitelist were reduced, however the basic concept of whitelisting was never removed, and it serves as a simply safety net to avoid confusion about the nature of transactions.

Smart Contracts By Example

Beyond the most common smart contract: sending coins to make a payment or to transfer funds, there exists a constellation of smart contract possibilities, with many complex transaction types even found in common use.
The most commonly used or promising potential uses for smart contracts are: multi-signature wallets, signature based escrow, coin mixing, group payments, payment channels, and time locked payments.
Generally speaking there are a simple set of primitives and logical rules that may be applied to form these contracts. Funds are controlled by private key values, which have a public key representation that is used as a public identifier. Fund values are represented by unspent funds from previous inward transactions, called unspent outputs. When forming a transaction, the unspent outputs are used to form the inputs of the new transaction. Alongside the fund transfer information is a statement regarding the preconditions of the transfer: limits on timing, signature strictness and composition are allowed to place intelligent limits on the fund transfer. The finalization of transactions involves two steps: cryptographically signing transactions with private keys to authorize the movement of funds, and publishing transactions to the miners to confirm transactions into blocks in the Blockchain.

CoinJoin Transactions

The concept of a CoinJoin transaction is to obscure the ownership of funds through a transaction in which many parties pool their funds in a single transaction, and then withdraw their funds from the pool in a proportional way, obscuring the Blockchain's chain of custody of funds: the Blockchain only cares about the balance of of funds going into and out of a transaction, within a transaction no linking information regarding the linking of funds in to funds out is necessary.
The way this leverages the scripting primitives is by taking advantage of the separation in the transaction formation step and the transaction signing step. The pooling transaction is passed around for all parties in the pool to inspect for its validity. After each party has signed, it is published to the network. Trust is not a variable in the equation because the signature each person applies can only be used in the transaction that they saw, alterations that would steal funds are prevented through the signature's cryptography.
These type of transactions are rare, but they can be found in the wild, most notably on the JoinMarket.

Arbiter Escrowed Transactions

In an arbiter based transaction, a trade is made in which two parties do not trust each other, but they trust the decision of a neutral arbiter to decide in the case of a dispute. This arbiter can be a person who evaluates the details of a trade, or even just a service or function that returns a signed statement that can be fed into a transaction. This kind of a transaction acts like traditional escrow, but with the advantage that the arbiter has no way to unilaterally take the funds for himself.
This type of transaction takes advantage of a transaction primitive called multi-signature verification. This statement can be setup to declare that some number of signatures are required to spend the unspent funds. In the prototypical arbitrated escrow situation, funds are given over to three people, with two signatures required to spend the transaction. This gives both the buyer and the seller an opportunity to refrain from signing until they are satisfied with their transaction, and in the case of a dispute gives the arbitrator the deciding vote to either refund or complete a transaction.
Escrowed exchanges are extremely common in Bitcoin, especially in instances like intra-platform trades on custodial wallets like ChangeTip, Coinbase, LocalBitcoins, Bitstamp. However these trades do not use arbiter escrow systems, due to the complexity cost of implementation.
Still, arbiter multi-signature transactions have some real world use. One example is enabling rapid fund transfers with BitGo's Instant service. Another service that is more classically in line with the arbitration model is Bitrated, which is something of a directory and marketplace for arbitrators.
Signed statement services and even standalone signing functions have been theorized as possible additional useful tools to use as arbiters, however in practice these have not found much uptake due to complexity, narrow scope, and lack of obvious necessity for their use.

Cooperative Multi-signature Contracts

One very simple scenario in which a multisig contract can assist in a trade is one in which a buyer does not trust a merchant to deliver and the merchant does not trust the buyer to pay. In this case a contract may be formed that states that both the merchant and the buyer must cooperate to finalize a payment over to the merchant. Once the buyer is satisfied, he signs the payment over to the merchant.
If something goes wrong, the buyer's funds are locked: not signed over to the merchant but not returned either. This gives the two parties motivation to come to an agreement to unlock the funds.
Although this type of multi-signature contract is quite simple, in practice it's rarely used. The properties of the failure scenarios when compared with adding an arbiter mean that arbiters are seen as a much more attractive option.

Security Multi-signature Contracts

The initial driving force behind multiple signature contracts was to improve the security of funds. A separation of signing authority is a security industry standard practice: simultaneously compromising multiple isolated systems is much more difficult. This security can power a scheme in which multiple independent personal devices are needed to sign off on a transaction, such as in the digitalbitbox hardware wallet's cooperation with a mobile phone app. Or it can create a voting mechanism between trustees, funds can be stored in a corporate wallet, with ten signatories but a mandatory signature limit of six signatures to send funds.
In practice, cooperative multi-sig is used quite frequently as a security precaution. Multiple signatures can make wallets such as Electrum and CoPay, or even Bitcoin exchange wallets like Bitfinex, much more secure by preventing single points of security failure.

Grouped Payment Contracts

One method of crafting a transaction can be to setup an aspirational send, a send in which there are not enough signed funds, but there is a known destination for funds. For example: several people together wish to egg each other on to participate in a bet. They can construct a transaction that has a known and unalterable output and transfer amount, but an undefined set of funding parties. These people can then allocate signed funds to the bet transaction, with confidence that the target of the funds cannot be altered and if the aspirational amount is not reached, the transaction will never complete.
In practice, situations in which this type of contract is apropos are few and far between. Due to the complexity of forming these transactions, few tools exist to make this workflow accessible for the average user and these transactions are very rarely seen in the real world.

Payment Channels

One promising Blockchain innovation powered by smart contracts is the concept of a payment channel. At a simple level, a payment channel allows instantly secure transactions at minimal cost by creating a secure channel to route transactions through. A transaction settled over a payment channel can be settled a million times faster and be a million times cheaper than a transaction settled on the Blockchain. Payment channels are only appropriate for repeated transactions between long running partners, however in theory a network of partners may be formed to allow sends between non-directly linked pairs.
Payment channels involve a series of smart contracts: a fund locking contract to lock in an amount of funds to trade, a time-locked refunding contract to avoid a cooperation deadlock between the payer and the payee, and then a series of balance update transactions that represent the rapid and secure trading of funds.
In detail payment channels are established through a careful protocol. First, the channel creator forms and signs a fund locking transaction that sends Bitcoin to an address controlled by both parties, but he does not share this transaction with the other party. Next, the creator creates a refund transaction that re-spends the Bitcoin from the fund locking transaction. The creator gets the other party to sign it, but the creator does not sign it himself so that only he can execute the refund. It's important to note that the refund transaction has a time restriction: it cannot be spent immediately, only after a period of time specified in the contract.
Finally, to create the channel, he shares the initial fund locking transaction with the other party, who can then sign and broadcast it to lock in the funds to the shared address. Because the creator has the refund transaction, he is safe from the other party not cooperating to return his funds, and because the refund transaction has a timeout, the other party has an assurance that the refund cannot be executed unexpectedly.
Now that the channel is established, the channel creator can start creating a new type of transaction, a payment channel transaction, which is like the refund transaction in that it re-spends the funds to refund the money, but updated with some funds now going to the other party instead of fully refunding himself. Each of these refund/payment channel transactions conflicts with the others, so double spending is impossible: when the other party wants to get paid, or the creator wants to end the channel arrangement, they simply take the last transaction and broadcast it to the Blockchain to settle the temporary balance of funds.
Channels need to be periodically closed and re-opened based on the expiration date of the time-lock. The time-lock ensures to the other party that the creator cannot back out of the contract unexpectedly or with an obsolete refund transaction. At the same time, the time lock guarantees that if the other party stops cooperating, the funds may be returned without their intervention after a period of time.
Although this protocol is promising for the rapid and economical advantages it brings, it is not yet in widespread use. The complexity involved in the protocol, complications from bugs and deficiencies with the Blockchain smart contract system, and the limitation presented locking funds to a single other party create large barriers to its use. That is not to say efforts have not been made. Developers have created libraries to abstract away the complexity of the protocol, such as in bitcoinj. Bitcoin Core has been progressively addressing the bugs and deficiencies that cause problems for effective channel use. And many efforts have been made to expand the protocol from single party payments to a network of connected parties.
Some examples of payment channels in the wild are the 21 Marketplace which provides a series of APIs that are paid over payment channels. Another commonly cited example is the Streamium streaming video service, which offers pay per second viewing of premium video content.
