Bitcoin is a form of digital currency which is based on an open source code that was created and is held electronically. Bitcoin is a decentralized form of currency, meaning that it does not belong to any form of government and is not controlled by anyone.
Bitcoin mining is analogous to the mining of gold, but its digital form. The process involves specialized computers solving algorithmic equations or hash functions. These problems help miners to confirm blocks of transactions held within the network. Bitcoin mining provides a reward for miners by paying out in Bitcoin in turn the miners confirm transactions on the blockchain. Miners introduce new Bitcoin into the network and also secure the system with transaction confirmation. They are also rewarded network fees for when they harvest new coin and a time when the last bitcoin is found mining will continue.
Bitcoins can be sold locally using LocalBitcoins, on Bitcoin brokerages / exchanges, using two-way Bitcoin Teller Machines (BTM’s) or you can pay for a good or service with them. Bitcoins can be sold to just about anyone as long as they have a Bitcoin address, and can be sold for any fiat currency in the world or traded for a physical good. Feel free to check out our recommended list of exchanges and brokerage services to sell your bitcoins online.
This is a yet another controversial topic. Because of the freedom and the degree of anonymity that the use of Bitcoin offers, many users who were seeking to purchase or solicit illegal goods or services initially turned to the use of Bitcoin as a method of payment.
Again, when a user decides to use a specific type of software for their Bitcoin wallet, they are deciding what direction the Bitcoin network is heading towards. In other words, you need the cooperation of nearly every single user in order to modify any aspect of the Bitcoin protocol.
