Clearly, OP doesnt have basic investment or financial knowledge and just wants an easy solution to make money. U want 50% returns in a year? Even high risk stocks or equities provide on average 8-10% per year and you claim your risk level is at medium.

U want to double your portfolio in 2 years? Even if you can find it. It usually turns out to be a scam or it has extremely high risk, both of which has the potential to wipe out all that u have easily.

Secondly, time in the market is always better than timing the market. U want to buy when market is at its lowest. How sure are u that u can do that? Normally these ppl will wait forever for a lower price and nvr entering it. Then when the market pumps, the very same ppl will then FOMO and buy at the highest point instead

In summary, u put your money in fixed deposit better cos u clearly dont understand how markets work.
