To be honest it is risky sometimes. I was thinking like holding is the best option , even if it falls i know it would go back up but i learned it is not the best opiton. You can make trades instead of holding to prevent stable loss. Otherwise it is like a gambit. You just have to wait till things get back to normal and we don't know when this happen.
When you invest with no knowledge, no matter what you invest in, you will lose. Investing in one way or another only reduces the capital loss.
