Bitcoin was official on the exchange in 2009

[CarreFenderc]

On 3/1/2009, Bitcoin was created from the first 30,000 lines of code. This virtual currency flows through a standalone software program.

There are only 21 million Bitcoins in the market, which are expected to be fully developed by 2040. At present, Bitcoin billionaire populations are now beginning to emerge thanks to the rapid rise in virtual money.

Just a quick correction, all of the bitcoins are expected to be fully mined at 2140, not at 2040.
