To me short-term investment ain't encouraging at all the risk in it alone is too much compare to that of long-term investment. Like for instance someone that lacks the ability to be patient (because I believe short-term investors are really impatient) , and endup buying bitcoin at the peak and then a massive dip followed it , that individual won't have the mindset to keep buying and holding instead he or she will endup selling in loss because they lack the patient, thinking he or she has cut their losses.
But for those that are into long-term investment, instead of selling in loss they will continue to buy the dip , because they believe in a long run they will endup with the last laugh , so they will keep accumulating and holding , and if later on the price's endup risen (surging) they will endup with a far better profits.
In this case, of course, many people have different opinions and of course there are many people who like to invest in BTC for the short term, but I see that in this case it depends on the person's skill in analyzing and considering the pros and cons, but of course if they have a lot of knowledge, it will certainly lead to profits because will buy BTC when the price of BTC falls and sell it when the price of BTC rises so of course you will get a profit from short-term investment in BTC.
However, for people who invest in BTC for the short term, for some people it causes panic when the BTC price falls, but for people who are experienced, of course when the BTC price drops, they will not sell their BTC and will not panic because for people who have experienced in BTC already know that BTC always creates new ATH and will not sell its BTC when it makes a loss.
But of course investing in BTC for the long term is the right step because of course it has the potential to get big profits. Yes, for example, people who bought BTC in the past when BTC was cheap and of course now the people who bought BTC in the past have made big profits. So I also agree that investing in BTC for the long term is a good thing as long as you use money to buy BTC using money are ready to lose and have to be prepared for the risk.
