You're not wrong, casinos have a model that works because in the long run, probability backs them. Math is powerful that way. But they also play on psychology -- offering +EV deals to gamblers like OP in the hope they are tempted by greed. It works the majority of the time but dare I say, OP has measures in place to mitigate his vulnerability to that psychology.

On a follow up note, seeing myself tagged now I feel I have to comment: I've been made aware of OP's challenges in keeping to the terms with some of his deals -- I have said I won't be involved; nevertheless I'm in touch with OP on several aspects, not least of all to prioritise closing all his outstanding deals. Another, is to account for the practicalities of fiat-crypto transactions at volume... a painful experience for the newcomer who will always overestimate timing. I'm hoping, a chastening experience for him as well.

Regardless, it's useful to have you and others post here to constantly remind everyone of the risks of lending.
