for small assets I think it's better for us to trade but it really depends on you whether you understand about trading or not, between investment and trading also has its own risks and we ourselves must be able to do things that I think the decision is in each of them , trading if you don't understand the instrument is the same
I think it depends on the situation. If he wants to gain his profit in a minimum amoun of time, he can choose trading, he can do day trading if he want some scalping can give him more money if he knows how to trade efficiently. But if he wants to make it longer invest it , I think investment has its own lock out period. But i think both tradind and investment are same thing, but with different risk.
