From what I've seen, success in this industry is predicated upon planning, caution, and constantly thinking of ways that people are going to screw you over.
Most people who break the law do so because they either don't consider the consequences or accept the rewards as justifying the risks. And plenty of criminals go to prison because they judged wrong. That those who are successful for long periods of time buck this trend is just survivor bias.
only as far as statute of limitations. figuring out the crime after that point is not a risk ... but it does put a target on your back
For a buyer, this isn't as big of a deal because you won't have that level of target on your back, but for anyone running a marketplace I don't think statute of limitations will protect you once they figure out who you are.
It bears repeating explicitly I think: you're not working against today's analysis tools, you're working against whatever analysis tools exist far into the future, since everything is recorded for eternity.
