Recently, Bitcoin has been quite volatile, and a friend of mine lost a significant amount because he didn't set a stop-loss. In fact, the most important thing in trading contracts is money management.

Let me share a little tip: For example, if you have 1 BTC in your account, don't open a position that exceeds 5% of your total funds each time, which is 0.05 BTC. This way, even if you make an incorrect judgment and get liquidated, the loss is still within a controllable range.

Additionally, setting a stop-loss is crucial! Set your stop-loss level before entering the market, and close the position decisively once it reaches that level. Remember, preserving your capital is essential to continue trading. What do you think of this advice?
