So, from a link on Threads about stock tips, I ended up joining a Whatsapp group, and like so many other groups, they quickly want you to deposit money into some platform that shares similar names to legit platforms, and then start recommending Buy or Sell of NAS100 or BTCUSDT, and it seems that, if their Buy/Sell suggestion is right, there is a lot of money to be made. However, I don’t trust the platforms that these recommend, and it doesn’t appear that one can legally trade these short-term contracts is USA? Can anyone explain to me if this is correct, or IF there is any way to trade these items in USA with a KNOWN LEGITIMATE agency/broker/platform please?
