Correct. Maybe I was too careless in experimenting with playing options without knowledge and playing carelessly at that time. I really gave up and will not repeat again. Fortunately, I was able to return my lost money through futures trading, because in futures, as long as our margins are small and the total funds we have in our futures wallets are quite large, it is safe for us to avoid liquidation prices.

The essence of what I am talking about is that our mastery of a form of trading in the market is our main weapon, both fundamental and technical analysis and strategy in trading. And as @FIFA worldcup said without all that we would lose money.
