These would be bitcoin users who have been bitten by BTC's lack of true fungibility, i.e. people who have had a coinbase account closed on them due to 'tainted' coins coming into their wallet from 4+ hops earlier, etc., even if they themselves never did anything questionable at all. Stuff like this that we all *know* is going to be impacting BTC adoption and actual real-world *use* more and more over time, especially as the so-called "chainalysis" gets stronger.
No, we all do not *know* stuff like this is going to be impacting BTC adoption and actual real-world *use* more and more over time. Speak for yourself, nobody elected you to speak on their behalf, and don't present your personal opinion as if it was anything better than just that. Over time everybody will have "tainted" bitcoins so your little theory is baseless. Besides, there is nothing easier than to launder your "tainted" bitcoins through any exchange, or just use any mixer.
