No matter how many companies and businesses support and see the value of crypto many people will not follow it. They have been ingrained to follow fiat currency. What people don't think of who use fiat is that your money is not backed by anything. It is just the agreed amount people say a piece of paper is worth. Same with crypto, it may not be backed but groups of people agree on its value.
