bitcoin is really worth it for me because comparing to fiat, the bitcoin increases the price, year by year, the problem with regular fiat currency is that governments can print as much of it as they like, and they frequently do. If there are not enough US dollars to pay off the national debt, then the Federal Reserve can simply print more.  Bitcoin is a relatively private currency. On the one hand, it is transparent – thanks to the blockchain, everyone knows how much a particular bitcoin address holds in transactions.
