The saddest part is that banks are not providing any services to list cryptocurrency projects on centralized exchanges, For which banks can issue new loans as well as create their own exchanges, These loans can help many failed projects, pump and dump tokens to list on cryptocurrency exchanges, For which no verification is required and people remain anonymous, Because banks can take their share in the form of tokens while issuing loans, the share portion can be equivalent to the loans they issue to such projects along with this to help them to get listed on exchanges, banks can support economies by providing liquidity to such projects by continuously issuing loans too.
Don't let's assume that banks are tge cause of many failed crypto projects, there are billionaires Investors among them who also move in money to make an Investment in them, if some of them get money from banks i think that's strictly for making business, the banks may be less concerned on what project they are embarking as well, just as you can also use your own reputation to get loan from the bank to engage doing any business of your choice, some projects developers are scammers right from time and were only taking the avenue for a new crypto launch to raise funds and pump the market then leave everything vulnerable all of a sudden.
