What I believe about bitcoin is that bitcoin is very sustainable and very trustworthy crypto currency and this is not hypothetical, bitcoin has made its existence since more than a decade and not made its existence but even has reached the sky high and become so successful that it is now superior of all the crypto currencies and because of its potential, it has provided employment to millions of people and helped them finding their jobs and I think foolish are the people who think bitcoin is a bubble that would burst soon or bitcoin is a fraud.
