I think holding is the best thing to do at the moment as the market price is not very enticing to make one want to sell. So holding till thing will probably stabilizes or get back up before one can think of selling.
The problem is that many people have become holders against their will. I traded coins and never sought to invest for a long time, however, due to the sharp fall in price, I was forced to become a holder.
OP is making it sound like trading is easy. It is not easy to trade and you have to learn it theoretically and from experience. You also have to keep your temper down.
For me holding is much easier but much less profitable then trading. (But more profitable then bad trading.)
