I've paid easy up to 20% if you factor in the fees from the fiat on-ramp i'm using like PayPal, lol its painful but I feel having a non-kyc stack is worth it
If I do see 3-5% premiums I usually jump on those, the other day someone was selling for 0 premium on robosats managed to bag it, said he was a first time seller, major score for me lol
Why should I pay premium? Where do you find a Bitcoin that's already KYCed? If KYCed, it's not Bitcoin. It becomes much the same as holding bonds or stocks, not the actual thing, and if you are stupid enough to think that you own any of the things under someone else's custody just by doing fucking KYC, it's nothing or less than nothing.
