Both trading and investment have risk, you should be aware that no matter how legit the company is there is always a risk of it shutting down.  And another thing, you should define on how much you wanted your capital to ROI, do you want a fast pace profit or the long monotonous payout?  There are investment that double your money but i may suggest that you avoid this kind of stuff, avoid cloud mining too.  It's kinda hard to suggest trading because you  need alot of research on this and this is accompanied by greater Risk,  I agree with yayayo, just try to find a job or  sell  goods and services.
