If you have good psychological quality and superb operating skills, then first of all, futures - high returns, high risks, quick results (provided you are a master)
If you have poor psychological quality and superb operating skills If it is too high, then I suggest stocks - the risk is relatively small, and the results depend on your operating level.
If you are a purely prudent investor, then we recommend funds - they are safer with less risk and slower results.
Finally, no matter which investment you choose, I wish you happy investing and good luck.
