corruption is one thing, I would call it merely unfair (unfortunately not illegal) to trade with inside information or by pulling strings. Crashing the dollar for personal gain, tho, it's practically treason.
BTC means they can pull wealth out of the system at astonishing rates. Trump & Co are hardly the first to be corrupt, but the scale, the blatentness, and the damage being done to the country as a byproduct is unprecedented in modern history
Bitcoin is arguably more public than stocks - all transfers are publicized. Transactions on major stock markets are publicized, but private transactions are not.
How do you think the SEC finds it's insider trading cases?
They see a giant position placed ahead of a movement in the market and then ask the exchange who placed those trades. The only difference between an exchange and crypto is that cypto you can also see.
