First of all move topic trading discussion board.

There is a difference between trading and investing in bitcoin. Trading is much more difficult and risk than investing most especially the future trading which involves margins or leverages. Adding leverage increases the reward of your holdings because it increases your position and it also increases the risk of liquidation.

As Someone without knowledge of trading even if you have with this small capital, I will warn you against trading and advice you to just create a custodial wallet and buy bitcoin and store there for as long as you want without the fear of liquidation

The exchange that you use for the future trading can be hacked
I do not think bitcoin can go below $40000 again but anything is possible
You may think to increase the leverage which might lead to money loss, that is future trading.
