i think by long term investment it mean 1 to 2 years of duration. and from short term investment it means the investment for hours and days. some tie i do long term investment and on regular basis i do long term investment i personally like short time investment. i do a little earning from it but do it continuously.
but i think that long term investment is much more good than short term investment because i also get a big profit from long term investment and short term investment can not make a good profit so i recommend that long term investment is good .
I agree that long term investment often leads to a great result. But be observant because not 100% of these long-term investments ended perfectly. Aside from waiting, how about invest your investment. I mean, you invested in bitcoin, and let your bitcoin grow by investing it on trading or ICO's of potential coins.
You need to buy good coins with good development team and community support. Otherwise, they will lose value.
