I quite like the way op has highlighted the need to decentralized exchanges over the centralized ones. The recent incidents in China shows the necessity of having decentralized businesses around crypto ecosystem. China was always against the use of virtual currencies and they were the first country to ban ICOs. So the market shouldn't have receive this massive shock we have experienced last week. But it's good that the market is now back on track and growth at a good pace. This incident will definitely push the decentralization to the next level and people have started realizing its need.
