I agree that it is problematic when anyone gets into bitcoin and they speculate that they are going to generate income through BTC, and surely it tends to take a long time to figure out some techniques that are profitable in trading, and most likely it is way better to build up BTC holdings through investment techniques prior to even trying to trade, yet if someone is trading, then they should limit their trading to ONLY less than 10% of their BTC holdings, and make sure that they are able to generate income from their trading before giving up other sources of income -and truly there are some traders who may well make money on their trading for several years, and then all of a sudden they get blown out of their position, which may end up showing that they really did not know what they were doing, even though they had assessed themself as knowing what they were doing.
If a person spends 4 years or more building his bitcoin holdings, then perhaps he might consider trading or ways that he might earn income off of his bitcoin holdings, yet even that could be problematic if the BTC stash is not of a sufficiently adequate size.
Well this only be proves one thing, and that’s the fact that no one can accurately predict the Bitcoin market or its price movement within the short term, sometimes predicting within the Long term may even seem somewhat difficult and that’s just the nature of the market, but most people have not really come to the realization of this fact and that’s why many of them delve into trading and attempting to predict the short term price movements, and the worse of it all is that that go in with almost 100% of their Bitcoin holding, probably due to impatience or seeking for easy profits and income.
Solely relying and depending on Speculations for income can in most cases be very misleading, and it takes even a longer period of time and experience to be able to tailor and develop a profitable strategy in both trading and HODLing.
But the truth still remains that accumulating and building Bitcoin holdings via long term investment still remains the best way to get involved in Bitcoin and should at all time take precedence over trading. But just like you pointed, if one must trade, it’s very important to play safe by limiting one’s exposure to at least 10% (or even less) of one’s total holdings, and very important, even if it’s not certain that one can absolutely and accurately predict the market at all time, at least make sure that you’re able to generate consistent profits before even relying on it as a primary source of income because not everyone are able to generate consistent returns and income from trading due to the complexity of the market and the volatility of the asset.
