Trading is very good if you are knowledgeable as you can keep increasing your capital more with that, but that does not make holding less good as well, considering the risk of trading, most especially without knowledge. If you think that you don't have skills and knowledge in trading and you're not a well experienced then cut it out as early as you can. Holding is the safest, yes the return of investment is quite slow but you can assure that you can still get it. Just do trading when you're an equip one that ready to go to war.
