Lets assume that starting in USA all bitcoin to fiat exchanges are banned. Will people be still interebitcoin 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 ??
I do think this is possible to happen. But if it did happened, there will be a lot of losses. This is because so many investors who are interested in converting bitcoins into fiat to make money will lose interest and find alternative means. This will drastically reduce the price of bitcoin and will eventually frustrate those that are interested in using bitcoin as a decentralized platform.
However, I believe that if this should happen, there will another way to convert bitcoins to fiat, probably not using USD as the middle currency and using a stronger currency.
The blockchain technology is improving day by day and it will surely find a solution to it.
