Sorry, but I think you're reading into my words something they didn't say or imply. In fact I tried my best to avoid wording it in a way that implies crypto is a scam (because I don't believe it myself).
What you've quoted strictly implies 2 things:
There are people who consider crypto a scam
Everyone will regard crypto as a scam after trump's future actions.
The 2nd is definitely an exaggeration, but neither of them claim crypto is a scam only that it has an image that it is - which I maintain it does with a significant portion of people.
I do think trump picked crypto as a target for his attention because it's a volatile and under regulated market he may be able exploit to try to make money off of whoever listens to him. I hope I'm wrong though.
