Don’t pursue the limit when making contracts. It’s enough to cut off the beginning and end and eat the middle. If you are too greedy, you will die quickly. Take a rest when you shouldn’t do it. Often when you think it is a good time to place an order, it is when the dog dealer exerts its strength, so never do it. Greedy for money you shouldn’t earn! ! ! #比特币市场波动观察 #加密市场回调 #萨尔瓦多增持BTC
