criptocurrency revolutions how be strong

Criptocurrency is now best (very low fee and fast) money transfer method.
these banks can destroy.so the banks take precautions.if there are those who want to translate the local currency into criptocurrency how to do it more easily.In the first place, the cryptocurrency markets should set up something like a cash dispenser to make this easier.
if they do it, the criptocurrency markets will both grow and they will be able to participate in this revolution.
this makes criptocurrency legal.
As a result, people can easily participate in this. Whenever they want, they can be converted to local currency and the appearance of an institutional structure also gives more people.
the only worrying side; when this happens, will the banks take over the cripple of cryptocurrency markets?
Thanks.
