The Bitcoin is the oldest and best known of all cryptocurrencies

Its inventor is Satoshi Nakamoto. However, it is still not known whether he is an individual or a pseudonym of a group.

Bitcoin was born out of the stock market crash in 2008. In 2009, the whitepaper on Bitcoin and its blockchain was published. Bitcoin is a digital currency that cannot be multiplied arbitrarily. A Bitcoin can also not be owned by more than one person at the same time. So if I own a Bitcoin, no one else can own it at the same time. Which is very much the case with our conventional money. If you want to know more about this, you should read up on the topic of fractional banking.
