there was some commotion about this and they finally named ethereum as number one!!! and as soon as they did this everyone started dumping ETH....
why do you think that is? was this a confirmation of its centralization?
The whole market is falling, and ETH too. Centralization? Dump? Lets see the most centralized - Ripple. Dumping from 8.5 to 6.9. And nobody cares Chinas ranker, ETH is still one of best cryptocurrency.
