Your willful lack of understanding is remarkable. There are non-scam uses of crypto, although I admit that there are more scams right now than non-scams. Regardless, painting all crypto devs as “scammers” is as absurd as painting political dissidents as “subversives” or “traitors”. It’s manipulative language, and it opens the door for classifying other software as “good” or “bad” based on highly flexible public opinion.
