I see that people support that altcoin suits better for day trading, and not for holding. I just don't get why.
because the price is cheap, and also the movement is fast, then altcoin is sometimes chosen for short-term trading. actually it depends on the type of coin. the reason is as above, people can get a lot of tokens at a pretty cheap price, and the increase can even change tens of percent in 1 day if the time is right.
