> 2) no one spends BTC
I'm awfully tired of these completely misinformed blog posts that seem to reflect HN's collective delusion about bitcoin. I don't know about US, but the whole drug trade, from the largest transactions to street level, have transitioned to crypto in Eastern Europe and at least few Middle Eastern countries. More and more of my friends who have never been interested in crypto as a ponzi scheme are using USDT to send and receive money across borders as their banks are hit with sanctions.
If you don't see something, it doesn't mean that it doesn't exist.
