Yes, Decentralized exchanges will be the future for exchanges of cryptocurrencies. It is safer than any third party sites like Binance, Bittrex, Hitbtc etc. People want to save his coins in his own wallet.
Decentralized exchanges in my opinion are safer and faster, because they do not involve third parties. Because all this time, third parties have always attracted high transaction costs, so that the greatest benefits are enjoyed by them.
