From the perspective of an analyst, any coin can open a contract. As long as the form is correct, draw an arrow and you can call the target price. I still haven't figured out what the underlying logic behind their arrow drawing is: there is no data statistics support or solid technical skills, but the charts are clean enough and the arrows are slanted enough. "The future will definitely rise to this point" has been said. From the perspective of a trader, most altcoins cannot be touched at all: if the depth is too poor, buying will result in losses; Fluctuations are too chaotic, plug in at any time. So, most altcoins can only slowly build positions in spot, reduce risks by building positions in batches, and then exchange for future volatility
