Binance has been so big and popular that a simple FUD about it could change the bitcoin price!
I'm not agree with centralize exchanges and if Binance doesn't create a decentralize exchange wouldn't last for a long time.
If you don't agree with centralized exchanges, then don't use them, it's that simple. Also, the 'decentralized' exchange Binance plans to set up isn't all that decentralized to begin with. I rather use current decentralized exchanges, or keep waiting for a better one, than making use of the BinanceChain. But who am I? People are free to use that what they like, and I'm happy for them they have the freedom to choose. At the end of the day, decentralized or centralized, everything helps increasing crypto's utility - without all these combined efforts, crypto would remain a joke for ever.
I used Binance because it has done so good so far and i don't know as good as decentralize exchange yet , I'd leave it as soon as i found one , i'd rather to keep the private key of my hand instead of giving to some exchange!
