Lets assume that starting in USA all bitcoin to fiat exchanges are banned. Will people be still interested in Bitcoins? I believe the applications of the blockchain are many, however, most people are attracted to Bitcoins because of its fiat value (or USD value). Deep under I believe that people are really not interested in the use of bitcoins in a decentralized platform/application but more interested in converting Bitcoins in to USD. Fiat currencies still seems to be the norm. Any ideas ??
Of course Fiat currencies have a preference, with a crypto currency, otherwise why then the cost of Bitcoin in dollars, if you can just compare with another crypto currency.
When Bitcoin is banned on exchanges, where it can be converted into Fiat, the crypto currency will be only digits in the purse in the Internet.
