As far as I can see, this also has a negative impact because it will further push the concept of centralization, which will reduce the benefits that can be obtained from decentralization. I just don't know if other communities here know this.
But the positive impact that it brings is that it will reduce volatility, and it will also increase transparency through the cryptocurrency concept. Last but not least, adoption will also increase, and when that happens, its liquidity and utility will also for sure rise.
