Today I thought for a long time again and found that the short-term trends in the future cannot be predicted at all, there are all kinds of possibilities. So in the next few weeks, if Ethereum does not continue to drop to my order price of 1570 USD, I must cancel this order at 1570 USD because the lowest bottom of Ethereum will definitely be below 1570 USD. If it hasn't dropped to 1570 USD within 5 weeks, once it drops, 1570 USD will definitely not be able to support the downward trend, so I must cancel the order at 1570 USD. Additionally, it is also very difficult to judge whether it can drop to 1000 USD. The only thing I am more certain about is that Bitcoin will drop below 50,000 USD. However, the short-term trends are really hard to judge. So the first bottoming out at that time can only be a rough estimate. The reason I want to place an order at the bottom is that I think after the first bottom, there will be a quick rebound, and at that time I can profit from a large wave. For example, if I can buy Ethereum at 1000 USD, after the first bottom reaches 1000 USD, there will be a quick rebound, leading to substantial profits, which can then accumulate the principal for the second bottoming. However, buying at the absolute bottom and not missing the opportunity is extremely difficult. But after the first rebound from the bottom, there will definitely be enough time to bottom out for the second time, but the bottoming out at that time will not have a quick rebound, so I can only hold the coins and wait for the next bull market. In summary, for short-term trends, even if I think hard, it is difficult to have full confidence. Short-term trends must consider various possibilities, so winning with short-term contracts is indeed very difficult. $ETH $BTC
