A Breif Note About Bitcoin
Bitcoin is a paperless, bank-less, state-less currency that allows people to pay directly for goods and services. The coins themselves are made by computers solving a set of complex math problems, and people who use their computers to make coins and record transactions are called miners.

The value of a bitcoin has fluctuated wildly since 2009 but now hovers between $400 and $450. To spend it, users buy bitcoin and transact using a third-party app such as Coinbase. Rather than a central authority validating transactions, all transfers are recorded on a public ledger. It can be used to pay for coffee, dinner or software from online stores as well as some real-world shops.
Bitcoin is a digital currency (also called crypto-currency) that is not backed by any country's central bank or government. Bitcoins can be traded for goods or services with vendors who accept Bitcoins as payment.

What is a Bitcoin and how does it work?
A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet.

How is a Bitcoin created?
A software developer called Satoshi Nakamoto proposed bitcoin, which was an electronic payment system based on mathematical proof. The idea was to produce a currency independent of any central authority, transferable electronically, more or less instantly, with very low transaction fees

The basics for a new user
As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once.

Balances - block chain
The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.

Transactions - private keys
A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining.

Processing – mining
Bitcoin mining is the process by which transactions are verified and added to the public ledger, known as the block chain, and also the means through which new bitcoin are released. Anyone with access to the internet and suitable hardware can participate in mining.
Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.

What is a crypto miner?
Mining programs tap into your computer's hardware resources and put them to work mining Bitcoin, Litecoin, or another type of cryptocurrency. And no, even if your hardware is used to generate money for them, you don't get any of it. They get all the money from putting your hardware to work.

What is Cloud Mining?
Cloud mining or cloud hashing enables users to purchase mining capacity that of hardware in data centres. ... Bitcoin cloud mining, sometimes called cloud hashing, enables users to buy the output of Bitcoin mining power from Bitcoin mining hardware placed in remote data centers.

What is the hash rate?
Hash (Rate) ~ A hash is the output of a hash function and, as it relates to Bitcoin, the Hash Rate is the speed at which a compute is completing an operation in the Bitcoin code. A higher hash rate is better when mining as it increases your opportunity of finding the next block and receiving the reward.

What is bit coin used for?
