In future will the banks be able to exchange bitcoins?
Now we are exchanging from traders...but when (if) the popularity of bitcoin increase a lot then the traders will not be able to exchange such amount of bitcoins...so what about the future of bitcoin?
It depends, if more and more large companies start accepting and offering bitcoin as a payment alternative, many other smaller companies will also start accepting and using it. This kind of exposure and acceptance is very important for bitcoin to survive. Ofcourse the government also plays a major role in this and the buying process of Bitcoins will have to be made much more simpler than it is at present.
I think in present time some shopkeepers and general stores already start accepting bitcoin, therefore we can expect that in future more bitcoin companies and industries will also start using bitcoin and will also accept it as for payment. In fact bitcoin is in very early start and therefore we can expect that in future bitcoin will become as more and more popular and mroe stores will start accepting bitcoin as legal currency.
