As for trading, not that it is not a get rich quick, but you should use the money that you can afford to lose. The man may wanted to return that money, but crypto and meme stock trading landed him in prison.
I did not know meme stocks has become that popular like meme tokens that people would be investing that much into it with a hope of making returns to payback the borrowed money and still get profit left. This man made so many mistakes and we have people making same mistakes in the cryptocurrency market, meme coins aren't real investment.
If you pick interest in investing in memes then do so with only spare money, meme coins can vanish at any moment and also the price of the meme projet can dump just because of useless reasons because they can also get pumped for no tangible reason, they are just pump and dump schemes.
