That is definitely true and I think it stands for any investment. Since I am from a country which has a poor economy and isn't stable, it's always a thought to pull out/sell my investments to help me out with the situation. Fortunately, I am patient and I've never dipped because of some emergency and I never actually had to. But some people just can't meet ends with their salary so they sell even if they wanted to hold for a profit.
It would be ideal if everyone could invest and hold, but you can't really bet against the economic situation you are in.
i understand what you are feeling friends, difficult economic pressures really make it difficult for us as bitcoin investors to keep holding on, especially if you can't get another job out there then selling the bitcoins you have is your only hope for survival.
but you must be able to learn independently while in bitcoin, you can use the skills you have to sell works of art
(for example) or what services can you offer for a fee in cryptocurrency or bitcoin.
if indeed you don't have the expertise that you can use to make money independently
(by not selling the bitcoin that you have) then you should be able to take part in online classes that often appear on the internet, and try to get additional income from the internet through the skills you learn from the online class.
