I've no idea what that means, in this context. Who's the pied piper, and why on earth must he be paid, in this context?
I've no sympathy for the greedy losing their shirt, their homes, whatever, by gambling with crypto. But their being stolen from, is a whole separate matter. This is so straightforward that I can't imagine what scope there might be for confusion on this point.
I was commenting specifically on the conflation I mentioned above. As for this guy's sentence, I personally think it was well deserved, maybe too light given the sheer scale of fraud. But as a matter of principle I'm always open to accepting a much lighter sentence than I might personally consider appropriate, because, well let's just leave that at because. So if my sayso would reduce his sentence, I'd be willing to provide it. But not on grounds that crypto's risky, because that has zero relevance to this fraud.
