Bitcoin "Bitcoin (BTC)" is a peer to peer payment system that uses the same unit for accounting operations, to ensure the functioning and protection of the system uses cryptographic techniques, but all information about transactions between the addresses of the system are available in clear online.
Any payment between two parties takes place without intermediaries and irreversible — there is no mechanism of cancellation of the confirmed operation (including when the payment was sent to incorrect or invalid address, or when the transaction was signed by the private key that is known to other persons), means no one can block (to arrest), even temporarily, with the exception of the owner of the private key (or the person to whom he was known), but provided the technology multipoles allows you to bring in a third party (arbitrator) and implement "reversible transactions".
Cryptocurrency — in this case, it is kind of so-called digital currency, the creation and control of which are based on cryptographic methods and usually given the decentralized cryptocurrency, the functioning of these systems based on technologies such as the blockchain, directed acyclic graph, consensus-based registry.
Information about all transactions is generally not encrypted and available in clear, to ensure the stability of the base of the block chain transaction uses elements of cryptography (digital signature-based system with a public key, consistent hashing).
The main feature of cryptocurrencies is the lack of any internal or external administrator, and therefore, banks, tax, judicial and other public or private bodies are unable to influence the transaction of any participants in the payment system (so cryptocurrency and became popular, because it is the best way to pay for all possible illegal goods and services), because of the sender or recipient of the payment is extremely difficult to identify and find even more impossible, this is as a result and the popularity of cryptocurrencies in the Internet.
Transfer of cryptocurrency is irreversible and no one can cancel, block, challenge or force (without private key) to make a transaction, but the transaction parties may voluntarily temporarily mutually block their cryptocurrency as collateral or to establish, that for the completion/cancellation of the transaction requires the consent of all parties.
The legal status of cryptocurrencies largely changes from country to country and is still undefined or changing in many of them, while some countries were allowed cryptocurrency transactions, while others have banned or restricted them.
The first cryptocurrency in the world is Bitcoin and it appeared in 2009, its cost was ($1 for 1309 Bitcoin), because in that time the cryptocurrency treated as entertainment and no one took it seriously from such a low starting price the world's first cryptocurrency.
