I would agree with you, but then I didn't say she was "against fraud". I said she was anti-crypto. Sure if you think all crypto is fraud then fair enough, but that's a pretty bold claim (and verifiably untrue).
As a first-order approximation, "all crypto is fraud" serves you very, very well.
Sometimes it's possible that it might not be fraud, but might instead be that you just lost your money because someone was incompetent instead. But then it's hard to tell when they are just lying about being incompetent to cover up the fraud.
Here's the thing: While I have nothing against drugs, and think them being illegal is ridiculous, the fact that they ARE still illegal means that those who sell them are, by and large, not nice people. Giving them money is not a good thing.
