the bank is a pretty good place of investment or investment for our society this
Bank is not considered as an investment. It meant for storing your money(regardless of the interest, because that's bad)
If we think with the real situation then we can see Bank and Cryptocurrency going to mixing. I mean, Banks are going to accept cryptocurrency because they are understanding the value of the Cryptocurrency.
But, most of the time they are doing the opposite :^) They hate Bitcoin because it could make economy in certain country become worse.
