You seem to be describing someone who had overinvested into bitcoin, and another problem is that the kind of person that you describe sounds like a gambler, because the smart thing to do if you have concluded that that you might have over invested would be to take some value off the table, and then to resume with a more prudent approach in which you can stay more focused on your goal of continuing to accumulate in a way that does not cause you to get overly excited (or emotional) about your investment. Sure, it is difficult to set our positions so that we don't get emotional because sometimes it takes a while to build up your position in bitcoin enough in order that you can begin to feel less and less emotional about it. It takes practice to build your portfolio in a way to at least attempt to minimize the amount of emotion, even though we are likely not going to completely get rid of the emotion, especially if we might happen to be normal people rather than bots.
What you say is quite true, especially us beginners need encouragement to fight our emotions of lust when things are like this. I mean we don't have to take a stupid attitude when market conditions are bullish. Yes, we have to be able to resist the temptation of profit because we have done quite well building a portfolio from the past 1 year by buying and holding. But the most difficult period is fighting our desires and perhaps it will ruin an investment journey if we are consumed by the desire for short-term profits.
Of course every increase always gives rise to one reason for every decision where it comes doubt to buy because some of them are afraid of the decision they made. Maybe the important point here is not to check Bitcoin prices every day because that can trigger uncontrollable emotions.
When we have succeeded in collecting as many Bitcoins as we can, of course we have to be able to restrain ourselves because if we cannot restrain our desires, it will very likely take what we have invested so that we will lose the opportunity to be able to profit from what we have collect.
