That'd be a decent strategy for drug dealers hoping to legitimize their earnings, but I don't think there are any drug markets taking ETH yet; most of the drug profits are in BTC. It'd be pretty hard to exchange millions of dollars' worth of BTC to ETH in a purely anonymous way, so I doubt that the massive ETH raises have criminal sources.

Also I sorta doubt that Brendan Eich is a drug dealer :)
