I've said this on countless occasions before:

Trump is different from previous presidents. Previous presidents didn't make money fast enough, and weren't ruthless enough.
Trump got his breakthrough from the crypto circle—once you master one method, you can apply it everywhere.
After cracking the crypto market, he started engaging in insider trading across various markets.
I estimate it's divided into two parts: one is his own small insider trading operation (Trump initially didn't have enough capital, which is evident from his need to profit from both long and short positions, and he only paid back the tower's rent after a certain profitable trade), and the other is leaking information to one of the original big market manipulators (with information advantages, the big manipulator can hunt down other giant whales and major players).
They don't even bother hiding their tracks—they just go all in.
