I think that in the foreseeable future, the bitcoins will not be able to replace Fiat money, in my opinion, this is obvious. Many people are still financially illiterate, and cryptocurrency is an empty sound for them. Banks in their usual form will not disappear, but I think they will try to introduce cryptocurrency technologies and adapt them for their development. This should lead to a symbiosis of Fiat and the crypt or their parallel existence in banks.
Most likely it will be so.State-owned banks may not disappear,but private banks may disappear as unnecessary.When this happens it is difficult for me to predict,but it is likely that it will happen soon.(from 1 to 3 years)
I beg to dis-agree. I don't think that private banks will disappear as well. They are obviously funded big time by lots of investors with deep pockets so I doubt that they will allow it.
With that said, bitcoin can't and will not beat banks that's for sure. These institutions is already established, and has the backing off a lot of investors from behind so it's going to be difficult. Unless those investors liquidate all their funds and move to bitcoin but that is unheard of.
