EOS CPU prices have skyrocketed, with a daily increase of 3,694.72%

According to IMEOS, starting from 18 o'clock last night (October 2), the CPU price will rise every hour and half, and I don't know why. As long as it is not a high-frequency transfer or a frequent call to a smart contract, it will not have much impact on normal use, and EOS users do not have to worry too much.
