Doesn't really answer the Government's (legitimate IMO) question: "You just sold $25,000 of bitcoin on {US_Based_exchange}, where did it come from?" Mix it all you want, it wont save you from an IRS audit or other formal Government inquiry if they so choose. Attempts to obfuscate sources of assets on a completely public blockchain could probably qualify as money laundering, in and of itself. Its not really much different than the cash -> casino chips -> cash launder (which gets reported to the government, or is supposed to).
