content: computer monopoly money  What do you think every bank uses?  USD is already digital and online.  Difference is USD is run by the central bank federal reserve and Bitcoin is decentralized.  USD is used in crime, fraud, blackmail, drugs, undergound black markets, etc... long before Bitcoin existed yet people claim Bitcoin is bad when someone uses it to buy drugs or it's connected to some crime.  Lol.  USD has been used for bad things a million times more than Bitcoin.
