Personally one of the reasons I'm still 90%+ in crypto is because I do not want to pay sh*t in additional taxes. So paradoxically our enemy is helping us to do the right thing (HODL).
That is a big challenge for Bitcoin holders. We need sometimes to exchange our money into fiat, but there is a risk to be taxed. That is not fair! A strategy is to exchange only small amounts of Bitcoin into fiat, then some time later more a small amount...
That is an incentive for sure (to continue holding), but we could need this money anytime in fiat for some emergency situation for an example. But if you don't need this money in real life, to continue holding is the best option. Who invested last year made 1000% profit just by holding, very possible for an ordinary man to become rich this way with a medium investment on that time.
