Bitcoin, the world’s largest cryptocurrency by market cap, was created in 2009. It gained popularity by promising lower transaction fees than traditional online payment methods. Users and investors also liked its independent status, i.e., it isn’t controlled by a central authority like a bank or government-issued currency. Also, it’s impossible to double spend a Bitcoin and there are only a finite number of Bitcoins in the world.
