...What CEX has as an advantage is the fact that there is a company and owners that profit and then can use that profit to improve the website...
I believe that it is by this parameter that there is no difference between DEX and CEX, since behind each DEX there is a project team that works on the development and maintenance of a decentralized exchange. It is enough to recall such decentralized exchanges as 1inсh, Uniswap and Pancakeswap, which regularly delight us with their updates.
