The real one is promoting crypto by playing a "foolish" version of himself on camera in exchange for money.

I don't see anything wrong there. He got paid to make an ad, and it's clear that's what it is.

If he was promoting FTX on his own personal account like so many "influencers" do, then I would be ok criticizing him.

I loved these commercials but they failed to convince me to put any money in FTX, or crypto altogether.
