does anyone know if coinjoin , wasabi, whirpool technology prevent tainted coins from entering mix pool?
Most services actually prohibit CoinJoin transactions as they're pretty easy to detect, whether it's tainted or not. As said before, unless you're able to pay some Bitcoins to a miner for newly mined coins, there probably isn't a way around it to get 100% untainted coins.
Think i heard that before some where, so you are confirming for me - useful and appreciated. Long time - self mixing may be the best.....thanks again
