It's just a matter of risk preference. If you're willing to make the decision to trade with 20x leverage, it means you have to be prepared for the looming risk of liquidation at any moment. Keep in mind that Leverage Trading or Futures Trading markets are a bit different from spot trading markets, so their movements are also a bit distinct.
I see it as gambling, not trading and trading or gambling, you must afford lose before doing it.
20x leverage is very big risk for your money but if you are ready, want to take big risk with hope that you can get bit profit, I wish you will get enough luckiness but I am not ready to do this.
To learn a lesson, it's best to increase risk gradually, starting with low leverage first. Once you're confident in your trading skills, you can then use higher leverage. Never get greedy in trading with leverage, as it will only make you lose control, and it's one of the quickest ways to self-destruct. High-leverage trading can also lead to addiction.
No, I don't agree with this suggestion.
When you use leverage, you always start with low leverage, then you will lose control and increase your leverage higher and higher. Eventually you will be rekted by the market and forced liquidations.
Your suggestion is increase low leverage gradually to higher leverage, that I disagree completely.
