16 months after the China mining ban which saw hash rate drop by ~50%, followed by a ~70% market correction in $BTC, hash rate is pushing new highs.
Miner revenue per TeraHash is approximately down 80% from its 2021 highs and headed for new all time lows.

What does this mean for bitcoin?
1) Miner margins are squeezing hard
2) The marginal production cost of $BTC has never been higher (although being impossible to exactly measure) $BTC is the only commodity in the world that becomes harder to produce as more people try.— Dylan LeClair

Price Impact is something all DEX users deal with on a regular basis. It refers to a price change occurring during a swap and can sometimes lead to unexpected losses.
But why exactly does it occur? pic.twitter.com/tKhGLhHYM8

Many decentralised exchanges use the x*y=k formula, where x and y are reserves of two tokens and k is constant, to price assets in their pools.
To find a relative price of a token in a pair, we simply need to divide x by y or vice versa.
— Trader Joe
Let's say there is an AVAX-USDC pool with 1000 USDC and 50 AVAX in it. In this case, x is 1000, y is 50, k is 50000, and the implied price of AVAX is 1000/50=20 USDC.
Alice wants to buy 100 USDC worth of AVAX and expects to get five tokens back.
— Trader Joe
In reality, however, she gets much less. Because Alice deposited 100 USDC, the x is now 1100 (was 1000), and y is 50000/1100=~45.45.
Instead of getting the 5 AVAX that she expected, Alice only received 4.55 (50-45.45).
The new price of AVAX is, therefore, 1100/45.45=~24.2 USDC.
— Trader Joe
So Alice paid almost $22 compared to the quoted price of $20, resulting in a price impact of ~9.8%.
If price impact didn't exist, Alice could have bought all 50 AVAX in a pool for a total of 1000 USDC, leaving no more AVAX for future traders. This isn't ideal. pic.twitter.com/ztQuyRe3vf

However, such a significant price impact isn't ideal either. So was there something Alice could have done differently?
Her swap was 5% of the size of the pool, so she would have gotten a better price by either finding a pool with more liquidity or by performing a smaller swap.
— Trader Joe
Alternatively, she could have used a DEX with a function different from the traditional xyk. For example, there are exchanges tailored towards stablecoins with reduced price impact.
Concentrated liquidity can also help, due to its capital efficiency, enter Liquidity Book (LB)… pic.twitter.com/HVqJsKQAae
— Trader Joe
LB introduces Discretized Liquidity. Liquidity is separated into constant sum price bins with their own bonding curve.
Because each bin has a fixed price, price impact while swapping only occurs during bin changes. Therefore swaps within 1 bin will incur 0 price impact. pic.twitter.com/aTjXmBEfSN
— Trader Joe
Overall, price impact remains one of the biggest topics in #DeFi and #DEX design.
There are various different ways to minimise it, but traders must still stay vigilant when performing swaps, lest they want to end up overpaying for their tokens.
