Trading Futures is another level. Why would you risk money here if you don't know how's the difficulty here. And futures is really a gamble. Even with how professional you are, there are chances that your funds will be burned in Trading Futures.
I believe by mentioning another level, you are referring the complexity of futures trading; because sometimes by another level most people are understanding like it is superior than what we are currently doing in spot trading. And I agree that even for professional traders predicting market direction will be too hard hence it is true with the statement of professional traders also facing big frustration in futures trading.
It's different from Spot Trading where basic knowledge about trading is enough before someone can start on it.
I'm just seeing that it's a misconception about spot trading. Maybe spot trading is less-cruel than futures trading still you cannot approach it easily. You must make sure you are having enough skill before starting with spot trading as well.
