I see short-term investors as those looking for daily bread, while long-term investors are those with goals , targets, and financial visions. They can quit any form of enjoyment and merriment and bag lots of bitcoin because they believe that in the future they will be financially free when inflation and purchasing power catch up with those stacking fiat.
those who are finding their daily bread in their investment are traders (day traders) while investors focus mainly on the future. That why as an long-term investots you have to have good sources of income that help preventing you from depending on your investment, but to help you in building a good and smooth investment.
Taking profit from your bitcoin investment is bad. It is the same thing as gambling because if you sell your bitcoin at a high price, you will need to wait for the bitcoin price to drop to a certain price before you can buy it back. But if the bitcoin price keeps going high, FOMO can make you lump sum on bitcoin so that you will not miss out or you end up losing hope of buying back because the bitcoin price is too high.
exactly craping from your investment always is not actually smart, you can do such if you know that you have gotten far with your bitcoin accummulation like hitting a certain goals in your accummulation. But if you have still new you accumulating like you haven't gotten that much stash in your portfolio, it would reduce the chances of you making good profits, just as you guys said your profits making depends on the bitcoins you have stash in your portfolio.
