BASED PONZI yall liquidity provider and thats it ser fellow degens, oh dude fat liq brings whales, ok but im poor so just make a ponzi where liq goes higher every time and boom whales will ape lmao.
10% tax to liq, 1% treasury, 90% supply burned at launch, where we feed the creators, bring influencers aproach whales with some love, that stuff bros.
LIQ will be locked at 50k cap, if you dont like dont ape mf.
i dont care for socials for now, i dont want tg, i want fat liq bruh so whales that are watching get boners.
