Bank try for stopping how bitcoin and altcoin is drop and make investor keep hold their money in bank and keep away for holding in bitcoin or altcoin as their asset, we know why bank against for bitcoin and altcoin e currency.
I think the bank is only afraid when its customers leave the bank and choose to save money or assets in the form of cryptocurrency or digital currency so that when that happens the bank will go bankrupt and no one will use the bank to transact or save money.
