Pump.fun Update Targets Creator Manipulation as Meme Coin Losses Mount

Viral on-chain data circulating on social media claims that over 95% of Pump.fun users lost money trading meme coins — and while that figure may be overstated, the reality isn't far off. According to verified reports, at least 50.6% of wallets trading Pump.fun-launched tokens recorded net losses, with only two wallets ever crossing the $1 million profit threshold. This lopsided outcome mirrors patterns seen in the previous crypto bull cycle, where meme coin speculation is widely credited with suppressing the broader altcoin season that many investors anticipated.

In response to growing criticism, Pump.fun co-founder Alon announced a protocol-level update designed to curb two specific types of market manipulation: vamping and griefing. Vamping describes behavior where token creators dump holdings into rising buying pressure, effectively extracting value from the community. Griefing refers to disruptive actions that erode trader trust, such as abrupt changes to token mechanics or fee structures mid-cycle.

The core change restricts how creators manage fee distribution. Previously, creators could redirect earnings at any point in a token's lifecycle — even after it had built significant momentum — which frequently triggered panic selling and community fallout. Under the new rules, creators are granted only a single opportunity to adjust fee settings. Once used, that change becomes permanent unless a more complex governance process is initiated. Existing tokens have been retroactively updated to comply with the same constraints.

The update signals a meaningful step toward greater transparency on the launchpad. However, it falls short of addressing the structural issues most responsible for widespread losses: token oversupply, early insider advantages, and rapid liquidity extraction by well-positioned wallets. Until these root causes are tackled, Pump.fun's trading environment will likely continue rewarding a narrow group of insiders while the majority of retail participants absorb the losses.
