Yes, I agree there are two many exchanges and some of the are saying that they are centralized and other decentralized. Most of them to my knowledge are simply scams and unfortunately some ICOs are boasting that their coin will get listed soon and give the investors an exchange that has no credibility and never heard of. This is too much and I believe it is detrimental for the future of cryptocurrencies and ICOs. The blossoming of so many exchanges irrespective if they are centralized or decentralized should be controlled and monitored.
