Lets assume that starting in USA all bitcoin to fiat exchanges are banned. Will people be still interested in Bitcoins?
Bitcoiners are not only found in USA or people from US will still find a way so they can still join the market and do trading.
I believe the applications of the blockchain are many, however, most people are attracted to Bitcoins because of its fiat value (or USD value).
Companies are attract to blockchain and there's another news that
George Friedman said: Blockchain Will Be Obsolete.
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 ??
This is your opinion and you are generalizing people to have that thinking which we are not sure of.
