So, yeah, like you are seeming to say nara1892, there can be some advantage to finding some kind of an investment point in which you are feeling sufficiently aggressive in your investment into BTC because if you are too whimpy, then even if BTC goes up a lot, the whimpiness of the investment may well end up not making up for the fact that the there really was not enough there to actually make meaningful profits, and a similar thing could be true for those people who end up investing too much, and then when the BTC price moves against their position and then fails to go up for a long time, they end up getting reckt.. or maybe even having to sell a lot (or maybe even all) of their BTC.
So yeah there may well be a decently broad range of balance that still is going to be able to work in order to become richie as fuck (without guarantees of course), but at the same time if you are either too far on one side (such as too whimpy) or the other (such as too aggressive) then you end up either not really profiting with any significance, or you end up losing most or all of your investment (or having to start back up over again from a worse position than if you had been more prudent and conservative rather than gambling with your investment into bitcoin by engaging in overly risky conduct).
So in this condition, if I look at the overall strategy, it is clear that it is very important in this regard. Indeed, in some cases being greedy especially for bitcoin can still be said to be good but of course there are strategies and moments that must be seen because not all greed to be in bitcoin can be good and one of the reasons is as you said when everything is too much in terms of "crybaby or aggressive" not everything will go well.
On the other hand, standing too far and leaving is also not the right choice, we need to balance this so that in the end we can be wiser in taking action and taking advantage of every available momentum.
