First, to conclude, #事件合约 is suitable for those with a main force mindset, strict position control, neither arrogant nor impatient, people with limited capital who play until reaching their goal and then switch to $BTC for stable profits.

Many people say event contracts are gambling, I don't argue, but I want to tell you there is still a glimmer of hope. To elaborate:
Why do I say it's gambling? Because the market itself is inherently unpredictable; no matter how skilled you are, it's impossible. Have you done enough review and analysis, breaking down candlesticks and combining them carefully to find the turning point? Do you understand the current main theme from a big-picture perspective, or are you just following the direction based on candlestick patterns? These are basic skills, and you can only seek inward; no one can help you. Transitioning to contracts later on is also essential. I collectively call these the main force mindset, and with this, the win rate is generally around 60%-70%.
Next, let's talk about position control, which is equally critical. No matter how high your win rate is, if you do it poorly, it won't matter. I won't elaborate on Martingale strategies here. When playing event contracts, strict position control is a must. For example, if you only have 400 USD, then each trade should be 10 USD; it's up to you, but I think at most 20 USD. Then, with 440 USD, 11 USD, and so on, gradually compounding.
Secondly, avoid arrogance and impatience. Don't get cocky after a few wins, and stay disciplined because you will inevitably have losing streaks. How proud you feel after winning, how painful losing streaks are. In the end, emotions take over, increasing your position size, continuing to lose, going all-in—dead end! Moreover, in this irrational state, you're just doing it for the sake of doing, unable to calmly wait. The win rate becomes unstable and very low, easily trapped by obsession. This is a hurdle you must overcome.
Once you meet these three conditions, stable compounding is basically guaranteed; only a matter of time. After that, you can choose to continue with event contracts or switch to futures to climb higher. After all, event contracts have limitations (5 trades, each up to 250 USD). At this point, you'll find trading futures really comfortable. You can do ultra-short trades very skillfully, and with some adaptation, you can also do medium- and long-term trades because candlestick levels are nested. To do well in medium- and long-term trading, you need a solid ultra-short foundation. If you have time, monitor the market and do short-term trades; if not, focus on medium- and long-term trades—very flexible. This is just my personal opinion, for reference only!
