Truth be told, hodling crypto currency is more about holding than anything else.
I think we all can agree on that but there is a small catch.
Those who have mastered the art of hodling have made the most money trading or investing in crypto currencies. The most basic skill one should have is HODLing.
Yeah, you do need to sell from every high to cash out some into fiat or stablecoin and then use that to buy back at lower price. If you dont do that, your total stash of bitcoin will never multiply, only the projected fiat value will show as big on your bitcoin wallet.
This cycling of bitcoin<>USDT/FIAT should be done with a fraction of the total bitcoin that you own. For beginners, this is a difficult thing to manage - but to make it simple, like in this current scenario, bitcoin is bearish, hence buy bitcoin to sell at a higher price. In the middle of the change, hold.
