It depends to your taste because there is people who is good in trading and good in holding. But both is good because you are earning money what ever you choose between the two the question is for the person who did one of that if they earn money because it is need patienced and a lot of hardwork and also a capital for investing.
I think depending on the moment and now investing is the trend that helps investors make the most profit. Of course, not every coin will be so profitable because most will depend on the situation of the market and the price of Bitcoin will decide it all. Trading for me is the fastest way to make money because I have a lot of free time and with the right strategy you will become very rich.
