Martin Shkreli went to jail for fraud, then got out and got into crypto.🙂🙃
Shkreli then allegedly did things that would have been big problems in traditional finance, but were completely OK in crypto.

Jail is not an effective deterrent. The right levers to stop these things are in other places.
If we want to protect future victims from harm, we should do that directly. Eg, Shkreli is not allowed to work in Pharma or securities.
