The strange thing is the proportion of mixing coins that comes from gambling.
Yeah, i for sure thought that would be higher considering Coinbase et al don't seem to accept coins from certain gambling sites, or so have i read, while they don't have a problem with mixers.
You'd think more people would mix their coins coming from gambling sites.
But perhaps it's a very niche market and they don't take up a big % as a whole either.
I would be curious to know where the mixed coins end up, specifically the percentage of mixed coins that end up at DNMs. The article briefly touched on this, but it doesn't appear to be addressed in the chart; I would also like to know the percentage of mixed coin that is proceeds from ransomware.
I know there was a website which displayed all of Chipmixer's outputs. Combine that with some wallet identifiers (Walletexplorer etc) and i'm pretty sure someone could make a nice statistic. I'm quite curious too, but i don't think it'll be much different from the graph linked in the OP (minus the illicit and illegal markets) => mainly exchanges probably.
