What does tonyk's idea make sense for me?
Because it removes the illusion that our DEX is able to compete with CEX (Centralized EXchange).
Why will DEX always lose out with CEX?
CEX has the advantage of knowing the complete order-book, including short positions. By actively trading using this insider knowledge, the owner of CEX has an extra revenue stream, which DEX will never have.
And if a significant part of this extra income is used to prop up liquidity, CEX will always attract more people, as it has bigger financial power and it can offer better liquidity than DEX.
DEX is not able to cheat on its customers (by having access to the knowledge they do not have), and as most customers are not able to detect this cheating, they accept it as part of the game, and as a result CEX has an unfair competitive advantage.
For me tonyk's idea is smart because it eliminates this unfair competition.
