Bitcoin was introduced in 2009 and now it has been a decade and bitcoin has proved its existence since more than a decade and no wonder that it will further make its existence for coming many decades and by its fate and potential, it has helped millions of people around the world in finding their jobs and abking them to earn their livelihood and I think inspite of all these things, if anyone is calling bitcoin a bubble or a scam, these people are morons and the time will answer them all.
