The truth is that, altcoin are really not meant to ne for short term investment.. Coin serve for a specific purpose, and if youll just used it for jist gaining it dies not serve its purpise and making no sense. Consider that altcoin must be hold not just to produce profit but also to make sure the coin well go well in its cycle. But if you're really looking for a sudden-changing coin you might just consider to put yoir fund in Etherium. Btw, between kucoin and Nvst I'll rather choose Kucoin, I have red good feedbavk from it.
