Cheap and fast, without so many documentary requirements. I believe some people already are acknowledging such benefits.
However, the other side should also know how to deal with crypto so they won't be having problem as well.
If more and more people will discover such route, I guess, they will appreciate more the crypto market, and so further increase in demand.
But in some cases, we still need other banking services. Like handling of mortgages, time deposits and other financial services.
It is difficult to abandon the usual state of affairs, those who are used to the banking system consider it an integral part of a comfortable existence, in addition, there are many people, and now they are the majority, for whom cryptocurrencies are something too risky to deal with them. Perhaps in the future something will change, but it seems to me that banks will start issuing loans in cryptocurrency sooner than the banking system will disappear from our lives.
