Yes, I pay taxes. I don't typically settle these kind of transactions from volatile holdings like Bitcoin or Ethereum. I use stablecoin for that, so matters of gains or losses are dealt with separately (if at all, as the case may be).
The stablecoin is not in the local currency of course, but it's not different in any practical way from handling foreign USD payments.
