> People aren't allowed to change their minds?
Sure they are, but they should explain why they changed their minds. In the case of meme coins like $TRUMP, it's hard to defend crypto as an investment or as a currency, which leaves the obvious reason: it's a scam.
In the case of Trump, I'm sure he was all for crypto as soon as he realized that he personally could make money from it. Same goes for his NFT grift.
