This effect lessens over time. With major exchanges and derivatives platforms coming online in the USA, Japan and South Korea, do you think rumours about the Chinese government can have lasting effects?
I suspect the Chinese government sees the writing on the wall, too. They know that cryptocurrencies aren't going away, so shutting down the exchanges just staves off the inevitable. And it would handicap their fintech sector, too. They are trying to be a financial hub, after all. I think they were trying to cool the market down while they impose stricter regulations. It's manipulative, but like I said, this effect is lessening over time as China's influence declines.
