I don't think there's a strong anti-crypto stance here. It strikes me much more as a strong anti crypto-fanboy stance. I'm not saying there's no one on HN who doesn't like crypto. I just think that, as a technogy, the general sentiment is "it's not fully baked yet". When that runs head long into dogmatic refusal to admit to any problems with crypto as a concept or a particular currency, the sparks that fly may look anti-crypto.
