Bitcoins can exist without exchanges, but would you support the argument that the existence of exchanges are among the factors facilitating the popularity and accessibility that people have to bitcoins?
Bitcoin in another way round can exist without exchanges, and if it does it will be very difficult to have a Bitcoin transaction that will give you Fiat currency, because P2P is very hard before you can as well see the transaction with very big amount, i will tell you that exchanges is what means the transaction of Bitcoin with fiat currency to be very simple and easier for us.
Having an exchange actually makes bitcoin grow and you can even say rapidly because with an indirect exchange it will be a way to elevate bitcoin in terms of price.
This can be a quite important role, in fact, even though bitcoin can exist without an exchange, on the other hand, it would be great if there was an exchange, and now we are already feeling the impact of the current exchange.
That's the exactly the point i tried to rise, because it's very obvious that without an exchange Bitcoin will not be interested to some people to partner with, so the use or the establishment of an exchange is what really makes Bitcoin to be well known and many people began to develop interest. So it would have been very difficult from my perspective to convert Bitcoin to fiat currency if assume their was no exchanges.
