Depending on jurisdiction, and your net worth in cash deposits, well you very well are. In the EU each single
account is guaranteed up to 100k Euro cash, anything above that is quite often subject to bank specifoc guarabtees and insurances. Also, banks are, since 2008, undergoing regular stress tests. They
always have published audited balance sheets, have rules and regulations around the use of customer deposits, which again are controlled. Heck, even during the Wirecard collapse nobody lost deposited money as far as I am aware.
As soon as a bank fails to provide audited balance sheets, authoroties can step in and halt operations. Mainly to make sure customers deposits are still there and can be withdrawn by the legal owners. It is almost hilarious how Crypto is relearning, at a redicioulous pace, all the lessons tradotional finance and banks learned over the last 100 odd years. And still fails to see that all the answers are already there. In a sense, it is almost peak start-up cliche disruption. Can almost be a good thing so.
