Great post bro, I still remember seeing ads of Karatbars on facebook. I didn't get involved in that but I remember being rekt a small amount of BTC, I think it was about $50 by a company called USI Tech, they were selling shares which were supposed to appreciate with time but the company shut down with investors BTC .
That's why decentralization and controlling one's own funds is highly advised. I learned my lesson back in 2016, it's simple...not your keys not your coins. The recent crypto company collapses of FTX, Celsius , 3 arrows have spoken very loudly. Never trust centralization.
Thank you for sharing and enjoy the weekend ahead :}
