Uniswap was easy to make, since it's "just" an ETH-based DEX.
To pull off a DEX like the one Stakenet is being, takes 10x more time, but once it's successful, it will absorb a LOT of volume, due to convenience alone.
I have been waiting for a DEX that can do everything for a long time, and yet I am not happy with what we have got and it is obvious the community agrees with me as they keep using CEXs, I really hope at this point that someone does it, we do not really need that hundreds of exchanges pull it off, as soon as one project is able to create a very good DEX the rest will know how to replicate it if it is open source and that is when a new era in this market will begin as we will not depend on CEX anymore to exchange our coins.
