Bitcoin has been known to almost all levels of people over the last few years. Satoshi established a Bitcoin, but it does not recognize this person as a person. However, the basic process of Bitcoin is that it is a digital currency, which will deal with peer-to-peer transactions, only those who know about this transaction. Thirdly, no other media will work here. The third means refers to the bank or any other recognized person.
These can not be calculated at all. There is a medium called blockchain that acts as a laser book for bitcoin. However, it can be provided with privacy as needed. Now the question is, since the money is now being transacted without the bank, then at what time will there be no bank? If a country's central bank controls all the money systems in that country, then what will be the need of the central bank to overcome the success of Bitcoin?
