If you have a short-term target then in such volatile period, I would recommend trading in short as well as the long way in order to earn the profit in rising as well as falling market environment. I do a lot of trading, but sometimes it seems as though it would be just as good to buy and hold
Short are too risky for untrained trader. I would recommend to hold until the price will fit your plan.
In the beginning, there is a risk of loss of money in almost all the things but trading has actually got higher probability of risk. Still, you need to make the right choice by analyzing your capabilities and the knowledge which you have regarding the things and the thing which you think of is more interesting. I personally am in favor of holding of the crypto coins as compared to that of trading.
