I believe we can. banks are for deposit and withdraw of money. In crypto circle, miners can do the same with largely transparent information. who needs banks?
Yes, we use the bank to transfer our money, send and receive money. It is also possible for us to live with that crypto if it can completely replace the fiat currency and if the various users of the currency will use and accept the use of crypto such as stores, establishments, institutions, and so on. But isn't it better for them to just co-exist for the effective use of money, now we are thinking more about the ease and convenience.
