I've never understood the purpose of Bitcoin mixers. The use-case seems to be half-assed money laundering. You're concealing the source of money[1], without bothering to invent a plausible alternate source. It's at best like a petty criminal who "launders" his money by simply claiming to have found it.
[1]-Poorly at that -- do we really think the people who catch launderers of actual money will be stymied by the transaction log of your average tumbler? It makes way more sense to launder money by renting BTC mining hardware and electricity from someone who doesn't care where the money came from, taking a loss but effectively trading your "tainted" BTC for brand-new BTC.
