I agree with this one I have friends who invested heavily in Bitcoin and they rely on all their expenses on their investment, and when the bear market happens they have no choice but to sell at a loss their portfolio, if you don't want to sell its important that you have your own business or stable job so you can keep your portfolio and you can HODL until it until the bull run, where you are likely to make profit.
This is what is meant by not being able to control one's emotions and manage one's financial condition. When one has the courage to invest in Bitcoin, one must understand the risks involved and remain optimistic about holding Bitcoin until the price rises again, as it is now, if the economic conditions are not good. If not, then it's better to look for a job and forget about Bitcoin; don't touch Bitcoin at all so that when the price rises, you still have a chance to make a profit.
Never force yourself if you want to invest, because it will make you lose. Investing in bitcoin is a very good thing, but if it is done the right way, but if we force ourselves then we might experience something bad.
Even if our finances are in good condition, but don't even think about investing entirely. Because when the red market happens, then we must be ready with everything. We will certainly have daily needs, it must be prioritized, do not let something we do even become a threat to us.
