Yeah that's part of the whole lightning network debate. Full decentralized exchanges and atomic swaps is very interesting. Making the wallets more flexible for different coins would be good too. Getting people used to it all. I'm all for different cryptos specializing in certain things. But in order to get there we need to be way more decentralized. The crypto community also needs to fund the development of crypto for the 3rd world. Lets attack issues like lack of finance, liquidity, food, water...... I love how crypto can make social causes and real capitalism more compatible then before.
