Mixers don't work anymore, stay away from them.
Most likely because the forum has banned them? I am assuming that you've said that they don't work anymore because of the recent ban that has been implemented about them here.
I'd agree that one way is to convert your BTC into Monero and going on with coinjoin.
@OP,
https://kycnot.me/ might help you.
Nothing to do with that, it's just widely assumed now that Chainalysis and governments have technology that makes them obsolete, that they can track transactions through them.
Monero is open source and only costs 1% to convert to, 2% max if you convert back, so why not be safe and do that instead?
