You think promoting a shitcoin requires more skills than blowing things up without blowing yourself up?
More or less skill is irrelevant.
There are more people who can blow up an ATM (or be trivially trained to) and collect the cash from it than there are who could do similarly for a cryptocurrency scam. (Few, if anyone, make $20mm simply tweeting promotions for other peoples’ coins.)
I think most HN users would be above-average successful at white-collar crimes, especially if those involve technology.

The kind of explosives you would normally use for this are not difficult to handle or deploy, anyone with access to google can figure it out.

The ICO typically gives you a shitcoin in exchange. You technically get what you were promised. It's just that the utility for said shitcoin never appears, but that wouldn't count as a crime.
Making a blockchain-powered cat food company and raising tons of money from investors without delivering anything is not a crime either, that's the expected outcome for 90% of startups.
