For sometime now, I have witnessed the rising trend of decentralized exchanges following the advent of Etherdelta and Forkdelta, A lot of existing and upcoming exchanges are tilting towards Decentralized exchanges as many Crypto traders wants more control of their digital assets, Some favor this due to risk of hacks associated with Centralized exchanges unlike in Decentralized exchanges where you have the private keys of your assets.I most sincerely favor decentralized exchanges., it will be interesting to see what the future holds in this regard as competition continues to rise for both Centralized and Decentralized exchanges
