Market Making is an activity that in traditional markets is needed specially in the more traded pairs. If we review what are the more traded markets in the world. Forex is the largest and most liquid market in the world and specially Euro/Dollar. In 2010, it accounted for more than $3 trillion of daily trading. Liquidity is not equal distributed in all the pairs all over the world, because it will be very inefficient to do it. Thats the reason usually a lot of trading is related to Currency A - Dolar - Currency B. That is probably the most important assets in terms of providing liquidity.
To have liquidity of Dolars will impact in the liquidity of all markets. If we compare with Crypto Markets, probably ETH and Stable Coins is also in the center of all pairs. As I will say most of the trades usually rest in ETH or stable coins after trading other crypto asset.
If we want to deliver usuful liquidity I will say that we have to incentivice where we add more value or more efficienci for people who is using Balancer. If I will think about I will say that for sure that ETH/DAI/USDC will be one of the most important pools to deliver efficiency to our users. And not all the Pools, only the biggest one with less comision
Probably the Pool could be that one like this
What if we incentivice this concrete Pool to create the more important Pool for ETH/DAI/USDC. How much comission we will save to the trading users in Crypto?
To incentivice the biggers pools of the most traded assets we are delivering the most usefull liquidity. Probably we have to think in ETH BTC and Stable Coins. That liquidity for sure will be more usefull, and it can also impact the rest of the pairs.
In some way we have to incentive to create the most effiency exchange. If we achieve that, that will be the best way to invite to integrate Balancer as we will have the best price.
We can test with ETH/DAI/USDC in order to check that hypothesis.
