Bitcoins are not printed as like dollars or euros. They are basically produced by computers all over the world by using free software and are held electronically in programs known as wallets. Satoshi is the smallest unit of a bitcoin. It is basically one hundred millionth of a bitcoin (0.00000001). this basically enables the micro transactions that some of the traditional electronic money is not able to perform. The BTC price keeps on varying.
BTC price is often abbreviated by the symbol BTC and was the first example of what we now refer to as cryptocurrency. Cryptocurrencies are a developing asset class that can share some of the characteristics with the traditional type of currencies except the fact that they are purely digital and creation, ownership verification is based on cryptography.
Generally, there are two possible interpretations of bitcoin. There is a bitcoin token which is referred to as the keys of a unit of the digital currency that the people own as well as trade. You can keep your bitcoin token in your bitcoin wallet which is basically identified by a chain of numbers as well as letters. In case someone wants to give you some of the bitcoins, then that person will have to send it to your particular, public wallet address.
Also, there is a bitcoin protocol in which the distributed ledger maintains the balances of all token trading. Basically, these ledgers are huge files that are stored on various numbers of computers across the world. The network can record each of the transactions onto these types of ledgers and can then propagates them to all the other kinds of ledgers onto the network. Once each of the networks agrees that they have already recorded every correct information then the network will permanently confirm the transaction.
