I think that now, trading crypto is more necessary than before. When the market caps were just a few billion, its easy to see how trying to trade it made no sense with an upside of 10x-100x. But right now, BTC will not see a 10x for possibly a few years and maybe even a decade. It doesn't mean its a bad investment to just buy and hold, and I like your strategy of holding 10 BTC just incase things go to shit very quickly, but I also think that if we magically get to 100k in the next few months, it will be a good sell zone, knowing that lots will be selling, and then scaling back in at lower prices.
50% and greater drops from 60k is much more painful than a 50% drop from 5k. And for BTC to do another 10x, it makes overtake the value of all the gold in the world, and once its over 10 trillion market cap, I think the world is fundamentally going to be much different. At those levels though, those 50% drops would be ultra painful and life changing in a bad way for many people. So I do think some sort of trading and holding onto profits will likely be necessary going forward.
