What would happen if a large number of crypto users coordinated an attack on a bank – ie 10,000 people take out loans, credit cards, etc at the same bank for as much as they possibly can, immediately use it all to buy bitcoin, then never pay back the loans. Sure it would wreck everyone's credit, but crypto is on the side of collapsing the credit system. Would this be enough to collapse a bank? Depending on which bank it is, it could cause a decent rise in bitcoin price, further benefitting everyone who was involved.

Has this happened before or been discussed? I feel like I might have FBI kicking down my door tomorrow lol, but it's just an interesting thought I had after reading The Bitcoin Standard
