That means that the tenBTC price has to follow because you get ~1 tenBTC for 1 BTC at the automated market maker.
It is the hour of Adam. Adam LOVES to arbitrage.
He buys BTC with his BUSD, then tenBTC with his BTC and sells them at the tenBTC/BUSD DEX Pools. That means he bought in at $ 24,000 and sell at $ 40,000 to the pools with the old price.
For an easier calculation: Let's say he does this with 1 BTC.
He bought for $ 24,000 and sells on $ 40,000
=> $ 16,000 profit minus 2x ~1.2% transaction fee
=> total win: $ 15,488
On this trade the tenBTC holder earned ~ $ 875.16 (thats meant by win-win(-win) situation).
