As I would like to think, long-term trade is better than short-term trade, because short-term trading is so hard for a newbie trader. First time long-term trade suitable for you. Now get some best coin and hold until the price increase and try to learn day trading its so risky and more profitable good luck 
I also think the same thing. sometimes waiting is the best thing compared to the rush to sell it. So, investing in a long time will certainly be very good. well, but of course it won't be easy, because seeing price changes every day, and panic selling can make you very uncomfortable to hold the coins you have in a long time.
