Fees leave at the worst time
A pump.fun coin earns creator fees on every trade, and much of that volume happens on the way down: people selling. The fees go to one wallet, and that wallet usually sells too. The money a falling coin produces leaves it exactly when it needs a buyer.
Send them back in, at the bottom of each leg
Nadiro keeps the fees with the coin and gives them one job. They wait in a pool until the price is 20% under its high, then they buy. The tokens go to an address that has no instruction to sell them, so every 20% fall meets a buyer that does not turn into a seller.
A fall, not a timer
A buyback on a timer buys the top as happily as the bottom. A buyback on a fall only spends when the chart is already down. The 20% rule is in the program's code; until we revoke the upgrade key, that key could change it, and we say so on every page.
What it does not do
It does not stop a coin from falling, and it does not make anyone money on its own. It moves the fees from someone's wallet into the chart, at the moments the chart is weakest, and shows every buy as a receipt. Why 20%: small enough to happen on a normal day for a memecoin, big enough that the pool is not buying noise.
