It has been said countless times that Trump is different from previous presidents; previous presidents didn't make money fast enough, nor were they ruthless enough. Trump seems to have figured things out from the crypto world; one law applies to all laws. After navigating the crypto space, he began engaging in insider trading across various markets. It's estimated to be split into two parts: one is his own small insider trading (Trump initially didn't have enough capital, needing to profit from both sides, which is evident, and he only paid back the building rent after making a profit once). The other part is leaking information to one of the original big players in the market (with the advantage of information, the big player can hunt down other giant whales). They don't care about hiding traces; they just go for it.
