No—my point is that AMMs can deploy way more capital because LPs are OK with modest returns and are guaranteed their fair share of fills.
Retail investors, too, are better off trading against an AMM, because liquidity doesn’t tactically dry up.

I agree that professional market makers undercutting the spread do ruin this nice equilibrium!
The solution to this, as for so many other problems, is to have all trading in the world go through Uniswap

you should see what happens when a country implements 30bp fees.
(basically retail ends up gambling on options and everyone else trades futures since spot is too expensive.)

I’m curious why you think 30bp is the only fee possible in AMM?

AMM providers get destroyed without large maker rebates because they're forced to provide at the market, both directions, whatever that is.

even with 30bp taker fees/maker rebates there's significant money to be made each day trading against AMMs, just doing arbs.
If fees were lower, AMMs would lose even more to that.

Arbitrage profits are not equal to liquidity provider losses!

They are unless the person providing in the AMM strongly things that on long timescales the assets are mean-reverty
which I think is not really what people are trying to express
and if they are then AMMs make more sense
as long as the belief is both strong and very nonspecific

I just mean mathematically, in the short run, it is not a zero-sum game.
ETH price goes from $300 to $310, arbitrageurs trade and make money. Market price goes from $310 to $300, arbitrageurs trade and make money. Liquidity providers now have more money than they started with.

I’m assuming the arbitrageur is actually arbitraging—trading against Coinbase or whatever. So they make actual profits on the way up and on the way down.
The liquidity providers make money from fees. And since the price is back where it started, they make a profit.

but if instead price goes from 300 to 310 to 320 then the LP loses a LOT
why are you assuming it mean-reverts instead of has momentum?
I was just responding to the implication that because arbitrageurs can make money trading on Uniswap, AMMs must necessarily be losing money. Sometimes they gain money from it!

yeah not true if you believe in mean reversion, but it's the right prior

But what if the LP is indifferent to that outcome. Most people like averaging down.
Say the value investors :-)
Q is how big is the pool of folks who like averaging down. I suspect it is gigantic.
