Why can’t the stolen coins be sold? If they can’t then what’s the point in stealing them?
It only takes one connecting piece of data for the pseudo anonymity to become a complete history of every transaction you have done. This is one of the reasons crypto coins will never become currencies
you are quite wrong, I bought a computer from a neighbor with them as one example. I stopped using them because they are a PITA compared to my CC and already digital money. I still have "truly" anonymous monero too, mined not bought
If you think multiple wallets keeps you anonymous, I have a bridge to sell you
There do exist anonymous tokens, such as XMR and the like, but no one knowledgable would ever think coins with (public!) transparent ledgers were somehow 'anonymous', only merely decentralized.
