BTC ETH I think this question should not only ask whether the end of the contract is zero, but also whether the end of financial speculation is zero; Because many people think that playing contracts is so easy to reset to zero, can I make money by playing spot trading? In fact, whether one can make money or not has little to do with playing contracts or spot trading. The difference may be that contracts lose money or make money faster; My biggest loss in the cryptocurrency industry was not in the contract, but in the spot market. I lost about $300000 on the Trump coin, which I only played in the spot market, but ultimately lost $300000. However, I actually made money on the contract; Setting aside the various scam teachers on Twitter who make money as easy as drinking water, we need to understand one truth: making money is difficult in any industry, isn't it difficult to earn money at work? Just in the financial field, making money is a harder thing because it may seem like there is no threshold, but the threshold is actually very high; As for whether the contract can make money, my answer is yes, but the difficulty is very high. It took me more than 3 years to find a trading system that can achieve breakeven without losing money, and then spent more than a year optimizing it before slowly starting to make profits; If you really enjoy trading but haven't realized it yet, I suggest giving yourself some more time. Most people can't make money in the field of financial speculation without 3-5 years of real money and silver training. Even if you make money by luck, as long as you don't leave, you will lose back later on due to your strength; So I think this question is not just about whether contracts can make money, but more broadly, it refers to whether financial speculation can make money. If contracts cannot make money, even if you play in spot and stock markets, it is difficult to make money. The difference is that spot and stock markets lose money at a slower rate. Contracts may disappear in a month, while spot and stock markets can last for a year; Finally, for players who still want to play in the contract market, I have gained valuable experience from losing money; 1： Diversification of principal: I believe this is the most important trading principle when playing contracts. Since you are playing contracts, do not use all of your capital as margin. Any extreme market situation in the cryptocurrency industry can occur, and having only one chance or ten chances is a completely different situation for a contract trader; 2： Trading signal: Find an indicator or data that can roughly determine the stage of the market, whether it is about to show a trend, enter a period of oscillation, or the consolidation stage of the trend market. The accuracy of the indicator or data does not need to be 100%, because there is no 100% signal at all; 3： Leverage size: I don't think it's that important. High leverage comes with high risk and high returns. The extent of your leverage depends on what kind of trading system you ultimately develop. Therefore, it's not easy to say that high leverage is necessarily bad and low leverage is necessarily good. In extreme market conditions, even the lowest leverage you have will be liquidated; 4： Stop loss strategy: If you can find a good stop loss strategy, it is certainly perfect, but stop loss is often inhumane. Since it is inhumane, it is very difficult to do. The ideal stop loss is to minimize the loss, but many people's stop loss is multi order loss in the most panicked time and short order loss in the most FOMO time. Therefore, if you can achieve the first point, exchange the funds used to make contracts for 1/10 of your total principal each time, and with the support of a second high win rate trading signal, placing the stop loss slightly before your liquidation price is the simplest and most effective way to stop loss; I hope all those who are still struggling in the speculative world can quickly find a suitable trading system for themselves;
