Seeing Mr. Yi's content, I happened to be looking at the number of open contracts in ETH, and I can clearly see that the open contracts have been on the rise in the past week. If the previous rise was due to many investors being long, then the current rise is likely to be an intensification of the long short game, after all, the price of ETH has not changed significantly, but the increase in open contracts represents that investor opinions have begun to diverge.
