Besides this few points that i have stated, kindly give your thoughts on how to detect a likely crashing exchanges.
Despite what everyone says, it's pretty hard to tell so, just look back from Bitcoinica days to FTX, so the thing is:
- a crappy exchange in danger of being insolvent would show enough signs not to put your money there in the first place
- an elaborate scam that uses users's money for their plaything will probably go undetected until it's too late, see MtGox, Celsius, FTX.
And signs like users complaining that they can't withdraw their money means it's pretty late to do anything.
