This is the mind boggling part to me and many others like you. How do you mess up this bad when you were on top of the world and a billionare before age 30? Was it really not enough?
Not sure which exchanges are sane anymore these days, you can rule out pretty much anything with it's own token as being too high risk, including Binance. Coinbase went too big too fast and we saw extreme greed with them going public. Kraken seem cautious overall, taking fewer risks and doing things the right way?
Hard to say for sure.
