My question is, if someone mixes bitcoin using Wasabi or similar mixing service, are those coins considered “tainted” for every individual owner of those coins in the future?
For context… I often buy bitcoin peer-to-peer and I’ve considered using a mixing service to increase my privacy. But then I learned that some crypto exchanges do not accept coins that have been mixed. Of course this sounds ridiculous to me, but if mixing will limit my options in the future I’d rather avoid “tainting” my bitcoin since I’m not doing anything illegal anyway. Just curious how it’s possible to tell that coins have been previously mixed, and is it worth the chance that it may be more difficult to transact with those coins in the future?
