I recall feeling most worried about hacks resulting in loss of customer funds, including funds not lent out for margin trading. I was also worried about risky investments or trades resulting in depleting cash reservers that could be used to make up for hacking losses.
I don’t think I ever generated the thought “customer monies need to be segregated, and they might not be”, primarily because at the time I wasn’t familiar with financial regulations.
E.g. in 2023 I ran across an article written in ~2018 that commented an SIPC payout in a case of a broker co-mingling customer funds with an associated trading firm. If I had read that article in 2021, I would have probably suspected FTX of doing this.
