Trading is very simple and easy because I only see between buy, hold and sell.
Investment is too complicated because you have to know how private sale, presale, public sale work.
Then in investment there is also a whitelist and that must also be studied how it works because if everyone doesn't understand then our investment can end in failure.
Both needs analysis, Trading is not just buy, hold and sell.
But we must know about market progress, signal and prediction.
Investing is learning more, because we should learn about white paper, road map, join presale, etc.
But I think If we compare about both, It depends on your money and confidence.
If you confident and comfort in trading, do it.
But Investing will gain more profit, If we choose potential projects.
