But when I examine Bitcoin and other crypto coins, I see it not as a replacement of money, but just as a replacement of the central bank money printing. Because eventually, we'll all look for a place to keep our money safe (a bank) and someone to give us a loan on occasion.
This is really deep and requires a deep reasoning. As for the replacement of the central bank money printing, I will say to that , that blockchain can do that role as one key factor of blockchain is data preservation. But if whether there will be a replacement of central bank money printing, I believe at some point money need to be printed is it is still being in use.
On loan too, bitcoin can be given as loan to be returned for same value as at when received by the borrower and maybe interest too could be added in bitcoin.
