In my sight, trading is much profitable compared to mining, though both of this job are needs capital but I choose trading as one of the good investment.
This is my example:
If you invest in mining it took a long period of time before you recover your investment and also you just need to spent much electricity. Are you agree?
On the other side, if you invest in trading and choose one of the better coins you can easily recover your capital together with your income, also in short period of time you can easily doubled or triple your investment. Are you agree?
