Top Bitcoin Mining Site

might be your best bet as of this writing. I've used their services and they could provide you a decent amount of bitcoins BUT it is entirely dependent on the amount of hashpower you invest in to. As of this day, I could say that you can break-even in a year's time and profit from their onwards. They are offering a lifetime bitcoin mining contract with your one-time spend. As long as their venture remains profitable, then they're good. This may change in the future.
100% assured income.

Free Bitcoin

Do you wonder where you can get some free bitcoins? For many of us, the discovery of Bitcoin is like the discovery of organic foods. We can see the benefits of using them but find it difficult to justify the cost, and then there is the risk that we’ll be getting a bad deal since we don’t know what we’re doing.

In Bitcoin, it’s like every organic food store has someone out front, offering free samples. Also, there’s a library everywhere you look, but only a few of those libraries have any good information. The largest traders would benefit a great deal if everyone just jumped blindly into Bitcoin, investing large chunks of their life savings in the process. That would be just fine by them, but it’s unlikely to happen. More likely, people are going to get involved with Bitcoin either by necessity, by chance or because someone was willing to give them a few bitcoins to get started with.
Now, before we begin discussing the places out there to get free Bitcoin, let’s just be clear: there is no way to get wealthy without working or investing for it. It is impossible to make an income in bitcoins or any other currency just by clicking around on some websites. However, that being said, cryptocurrencies are unique in that clever marketers can make a profit doing exactly that, giving away money. This would not be possible in other currencies, where they simply can’t be broken down small enough. The operator will usually make less than a penny. If they were forced to give you a penny or more, there’d be no way to be profitable. Getting free bitcoins is not a way to get rich, and certainly not the most profitable use of one’s time, but if you’ve got some free time and would like to pick up a small amount of extra Bitcoin now and then, then this definitive guide will is a great place to start.

Why Use a Blockchain?

As the implications of the invention of have become understood, a certain hype has sprung up around blockchain technology.
This is, perhaps, because it is so easy to imagine high-level use cases. But, the technology has also been closely examined: millions of dollars have been spent researching blockchain technology over the past few years, and numerous tests for whether or not blockchain technology is appropriate in various scenarios have been conducted.
Blockchain technology offers new tools for authentication and authorization in the digital world that preclude the need for many centralized administrators. As a result, it enables the creation of new digital relationships.
By formalizing and securing new digital relationships, the blockchain revolution is posed to create the backbone of a layer of the internet for transactions and interactions of value (often called the 'Internet of Value', as opposed to the 'Internet of Information' which uses the client-server, accounts and master copy databases we’ve been using for over the past 20 years.)
But, with all the talk of building the digital backbone of a new transactional layer to the internet, sometimes blockchains, private cryptographic keys and cryptocurrencies are simply not the right way to go.
Many groups have created flowcharts to help a person or entity decide between a blockchain or master copy, client-server database. The following factors are a distillation of much of what has been previously done:

Is the data dynamic with an auditable history?

Paper can be hard to counterfeit because of the complexity of physical seals or appearances. Like etching something in stone, paper documents have certain permanence.
But, if the data is in constant flux, if it is transactions occurring regularly and frequently, then paper as a medium may not be able to keep up the system of record. Manual data entry also has human limitations.
So, if the data and its history are important to the digital relationships they are helping to establish, then blockchains offer a flexible capacity by enabling many parties to write new entries into a system of record that is also held by many custodians.

Should or can the data be controlled by a central authority?

There remain many reasons why a third party should be in charge of some authentications and authorizations. There are times when third-party control is totally appropriate and desirable. If privacy of the data is the most important consideration, there are ways to secure data by not even connecting it to a network.
But if existing IT infrastructure featuring accounts and log-ins is not sufficient for the security of digital identity, then the problem might be solved by blockchain technology.
As Satoshi Nakamoto wrote in his (or her) seminal work, "Bitcoin: A Peer-to-Peer Electronic Cash System": “Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable.”
Private key cryptography enables push transactions, which don't require centralized systems and the elaborate accounts used to establish digital relationships. If this database requires millions of dollars to secure lightweight financial transactions, then there’s a chance blockchains are the solution.

Is the speed of the transaction the most important consideration?

Does this database require high-performance millisecond transactions? (There is more on this point in our guide: "What is the Difference Between a Blockchain and a Database?").
If high performance, millisecond transactions are what is required, then it’s best to stick with a traditional-model centralized system. Blockchains as databases are slow and there is a cost to storing the data – the processing (or 'mining') of every block in a chain. Centralized data systems based on the client-server model are faster and less expensive… for now.

In short, while we still don’t know the full limits and possibilities of blockchains, we can at least say the use cases which have passed inspection have all been about managing and securing digital relationships as part of a system of record.

How Bitcoin Mining Works?

In traditional fiat money systems, governments simply print more money when they need to. But in bitcoin, money isn’t printed at all – it is discovered. Computers around the world ‘mine’ for coins by competing with each other.
How does mining take place?
People are sending bitcoins to each other over the bitcoin network all the time, but unless someone keeps a record of all these transactions, no-one would be able to keep track of who had paid what. The bitcoin network deals with this by collecting all of the transactions made during a set period into a list, called a block. It’s the miners’ job to confirm those transactions, and write them into a general ledger.

Making a hash of it
This general ledger is a long list of blocks, known as the 'blockchain'. It can be used to explore any transaction made between any bitcoin addresses, at any point on the network. Whenever a new block of transactions is created, it is added to the blockchain, creating an increasingly lengthy list of all the transactions that ever took place on the bitcoin network. A constantly updated copy of the block is given to everyone who participates, so that they know what is going on.
But a general ledger has to be trusted, and all of this is held digitally. How can we be sure that the blockchain stays intact, and is never tampered with? This is where the miners come in.
When a block of transactions is created, miners put it through a process. They take the information in the block, and apply a mathematical formula to it, turning it into something else. That something else is a far shorter, seemingly random sequence of letters and numbers known as a hash. This hash is stored along with the block, at the end of the blockchain at that point in time.
Hashes have some interesting properties. It’s easy to produce a hash from a collection of data like a bitcoin block, but it’s practically impossible to work out what the data was just by looking at the hash. And while it is very easy to produce a hash from a large amount of data, each hash is unique. If you change just one character in a bitcoin block, its hash will change completely.
Miners don’t just use the transactions in a block to generate a hash. Some other pieces of data are used too. One of these pieces of data is the hash of the last block stored in the blockchain.
Because each block’s hash is produced using the hash of the block before it, it becomes a digital version of a wax seal. It confirms that this block – and every block after it – is legitimate, because if you tampered with it, everyone would know.
If you tried to fake a transaction by changing a block that had already been stored in the blockchain, that block’s hash would change. If someone checked the block’s authenticity by running the hashing function on it, they’d find that the hash was different from the one already stored along with that block in the blockchain. The block would be instantly spotted as a fake.
Because each block’s hash is used to help produce the hash of the next block in the chain, tampering with a block would also make the subsequent block’s hash wrong too. That would continue all the way down the chain, throwing everything out of whack.

Competing for coins
So, that’s how miners ‘seal off’ a block. They all compete with each other to do this, using software written specifically to mine blocks. Every time someone successfully creates a hash, they get a reward of 25 bitcoins, the blockchain is updated, and everyone on the network hears about it. That’s the incentive to keep mining, and keep the transactions working.
The problem is that it’s very easy to produce a hash from a collection of data. Computers are really good at this. The bitcoin network has to make it more difficult, otherwise everyone would be hashing hundreds of transaction blocks each second, and all of the bitcoins would be mined in minutes. The bitcoin protocol deliberately makes it more difficult, by introducing something called ‘proof of work’.
The bitcoin protocol won’t just accept any old hash. It demands that a block’s hash has to look a certain way; it must have a certain number of zeroes at the start. There’s no way of telling what a hash is going to look like before you produce it, and as soon as you include a new piece of data in the mix, the hash will be totally different.

Miners aren’t supposed to meddle with the transaction data in a block, but they must change the data they’re using to create a different hash. They do this using another, random piece of data called a ‘nonce’. This is used with the transaction data to create a hash. If the hash doesn’t fit the required format, the nonce is changed, and the whole thing is hashed again. It can take many attempts to find a nonce that works, and all the miners in the network are trying to do it at the same time. That’s how miners earn their bitcoins.

How do Bitcoin Transactions Work?

Bitcoin transactions are sent from and to electronic bitcoin wallets, and are digitally signed for security. Everyone on the network knows about a transaction, and the history of a transaction can be traced back to the point where the bitcoins were produced.
Holding onto bitcoins is great if you’re a speculator waiting for the price to go up, but the whole point of this currency is to spend it, right? So, when spending bitcoins, 
how do transactions work?

There are no bitcoins, only records of bitcoin transactions

Here’s the funny thing about bitcoins: they don’t exist anywhere, even on a hard drive. We talk about someone having bitcoins, but when you look at a particular bitcoin address, there are no digital bitcoins held in it, in the same way that you might hold pounds or dollars in a bank account. You cannot point to a physical object, or even a digital file, and say “this is a bitcoin”.
Instead, there are only records of transactions between different addresses, with balances that increase and decrease. Every transaction that ever took place is stored in a vast public ledger called the block chain. If you want to work out the balance of any bitcoin address, the information isn’t held at that address; you must reconstruct it by looking at the blockchain.

What does a transaction look like?

If Alice sends some bitcoins to Bob, that transaction will have three pieces of information:
·         An input. This is a record of which bitcoin address was used to send the bitcoins to Alice in the first place (she received them from her friend, Eve).
·         An amount. This is the amount of bitcoins that Alice is sending to Bob.
·         An output. This is Bob's bitcoin address.

How is it sent?
To send bitcoins, you need two things: a bitcoin address and a private key. A bitcoin address is generated randomly, and is simply a sequence of letters and numbers. The private key is another sequence of letters and numbers, but unlike your bitcoin address, this is kept secret.
Think of your bitcoin address as a safe deposit box with a glass front. Everyone knows what is in it, but only the private key can unlock it to take things out or put things in.
When Alice wants to send bitcoins to Bob, she uses her private key to sign a message with the input (the source transaction(s) of the coins), amount, and output (Bob’s address).
She then sends them from her bitcoin wallet out to the wider bitcoin network. From there, bitcoin miners verify the transaction, putting it into a transaction block and eventually solving it.

Why must I sometimes wait for my transaction to clear?

Because your transaction must be verified by miners, you are sometimes forced to wait until they have finished mining. The bitcoin protocol is set so that each block takes roughly 10 minutes to mine.
Some merchants may make you wait until this block has been confirmed, meaning that you may have to make a cup of coffee and come back again in a short while before you can download the digital goods or take advantage of the paid service.
On the other hand, some merchants won’t make you wait until the transaction has been confirmed. They effectively take a chance on you, assuming that you won’t try and spend the same bitcoins somewhere else before the transaction confirms. This often happens for low value transactions, where the risk of fraud isn’t as great.

What if the input and output amounts don’t match?

Because bitcoins exist only as records of transactions, you can end up with many different transactions tied to a particular bitcoin address. Perhaps Jane sent Alice two bitcoins, Philip sent her three bitcoins and Eve sent her a single bitcoin, all as separate transactions at separate times.
These are not automatically combined in Alice’s wallet to make one file containing six bitcoins. They simply sit there as different transaction records.
When Alice wants to send bitcoins to Bob, her wallet will try to use transaction records with different amounts that add up to the number of bitcoins that she wants to send Bob.
The chances are that when Alice wants to send bitcoins to Bob, she won’t have exactly the right number of bitcoins from other transactions. Perhaps she only wants to send 1.5 BTC to Bob.
None of the transactions that she has in her bitcoin address are for that amount, and none of them add up to that amount when combined. Alice can’t just split a transaction into smaller amounts. You can only spend the whole output of a transaction, rather than breaking it up into smaller amounts.
Instead, she will have to send one of the incoming transactions, and then the rest of the bitcoins will be returned to her as change.
Alice sends the two bitcoins that she got from Jane to Bob. Jane is the input, and Bob is the output. But the amount is only 1.5 BTC, because that is all she wants to send. So, her wallet automatically creates two outputs for her transaction: 1.5 BTC to Bob, and 0.5 BTC to a new address, which it created for Alice to hold her change from Bob.

Are there any transaction fees?

Sometimes, but not all the time.
Transaction fees are calculated using various factors. Some wallets let you set transaction fees manually. Any portion of a transaction that isn’t picked up by the recipient or returned as change is considered a fee. This then goes to the miner lucky enough to solve the transaction block as an extra reward.
Right now, many miners process transactions for no fees. As the block reward for bitcoins decreases, this will be less likely.
One of the frustrating things about transaction fees in the past was that the calculation of those fees was complex and arcane. It has been the result of several updates to the protocol, and has developed organically.
Updates to the core software handling bitcoin transactions will see it change the way that it handles transaction fees, instead estimating the lowest fee that will be accepted.

Can I get a receipt?

Bitcoin wasn’t really meant for receipts. Although there are changes coming in version 0.9 that will alter the way payments work, making them far more user-friendly and mature.
Payment processors like BitPay also provide the advanced features that you wouldn’t normally get with a native bitcoin transaction, such as receipts and order confirmation web pages.

What if I only want to send part of a bitcoin?


Bitcoin transactions are divisible. A satoshi is one hundred millionth of a bitcoin, and it is possible to send a transaction as small as 5430 satoshis on the bitcoin network.
