By waves everyone can create a matcher for the DEX. In the future all those mathcers together will be used for the DEX inside the lite client.
I have thought before about buying bitshares, but I don't like how they ask 100 dollar and give people who pay big advantages about others. Besides that at the point I joined there discord a few weeks ago, the support wasn't really kind against other customers.
The truth is I wanted to invest in Bitshares, but there own staff and support made me take my money and move to waves. And in the end I am thankfull that they made me do this.
