That’s true. I’m not sure why people think that you do not have to pay any taxes for bitcoin. In fact, the IRS has expounded on how you still have to pay taxes for every bitcoin transaction you make and even just for holding. More details here from CNBC crypto:

This may not discourage the holders though. It only legitimizes holding btc so this won’t scare them anyway so long as they still get profit. I would honestly prefer to pay taxes rather than having to deal with a crypto ban in my country. It’s likely, however, that most hodlers are just evading.
