When making contracts, it is important to look at practical experience, estimate the price points and judge the direction. Doubling small funds is easy, but losses can also occur quickly. The core is how to choose the timing for entering and exiting based on market feeling. Position management is very simple; just do it strictly according to the requirements. The problem is whether one can control greed and mindset. Not everyone can decisively cut losses when they need to. If you can manage your mindset and timing well, making some profit in this market is really not that difficult (the market is always there; if you keep up, you can benefit from it) $BTC #主流币轮动上涨
