Sometimes trading could also give you more profit than investing.
It is all about skills, timing and knowledge if you could earn from trading why wouldn't you use it.
Why not use that skills and capital to earn rather than letting it sleep and wait for the profit?
No doubt trading requires skill, knowledge etc. Investing is different yet both are risky, for the fact there’s no risk free investment makes investing difficult most times, knowledge is needed yet even with the appropriate knowledge trading can be difficult compared to investing. Not minding the more profit you get after trade it’s easier to experience a loss when trading due to market fluctuation etc.
