The rules are the same for every coin and cannot be changed: 90% of the fees (they arrive in USDC) are paid to the holders by bag × time held (a wallet over 2% of the supply, or in a cluster, is paid nothing — yours included), 10% buy and burn $ATM, every 10 minutes. Standard pump.fun fees, no extra tax. Keep your dev buy under the limit if you want it to earn.
