Surely I have nothing against the idea and the actual practice of specialization, especially when it comes to something like trading - yet at the same time, even if one specializes in bitcoin (and bitcoin trading), generally speaking, it still is likely NOT very smart to trade an asset like bitcoin, except maybe small portions of your capital after you have a HODL stash.... so for example, if you think about bitcoin as an asset, it is one of the best (most pristine) assets in existence (and perhaps even the best), and even though it is quite volatile, it also has a lot of fundamental paradigm shifting qualities that cause a lot of ongoing potential for explosive upward growth periods in its price and the explosive growth periods are not very predictable, no matter how much you study bitcoin you might not necessarily see or appreciate the days that you need to have had been in bitcoin until they already played out an if you are not in during days that you should have had been in then you are left with less bitcoin than what you could have otherwise had... so yeah, traders can be cocky as fuck and even win 9 out of 10 trades, but then not be in on one of the trades and then end up losing most if not all of their earlier profits by not being in at certain times in which BTC ends up shifting up dramatically... so they are left with a dilemma to wait it out (which might not work) or to lock in their losses, which is buying back BTC at higher prices than they ended up selling... and these kinds of uppity explosive dynamics have taken place many times in bitcoin's history.
