Cupsey
Solana trench trader
Ongoing CT debate that his edge is partly copy-traders acting as exit liquidity; some posts allege coordinated copytrade wallets. These are unproven allegations/commentary, not established wrongdoing.
Cupsey of the most-watched Solana memecoin 'trenchers', a high-frequency flipper who buys brand-new pump.fun tokens seconds after launch and quick-flips them all day long.
Who they are
Cupsey is an anonymous Solana trader (reportedly a former Fortnite grinder) who turned round-the-clock pump.fun scanning into a spectator sport. He is famous for buying enormous numbers of freshly-launched coins, holding for minutes, and flipping, while broadcasting a 'the trenches are always open' work ethic to a large audience. He runs a curated 'avengers of Solana' Telegram group and is associated with the TrenchGrinders community.
History
Cupsey claimed to have cleared over $1,000,000 on pump.fun alone with, by his telling, zero insider or Raydium plays, and topped the OKX Wallet leaderboard for a three-month stretch with roughly $5.14M profit at a ~67.7% win rate. His wallets are among the most copy-traded on Solana, which itself became the controversy: critics argue copy-traders following him end up as exit liquidity while he quick-flips out. As of 2026 he remains one of the reference names any trencher-tracking tool (kolscan, OKX, KOL Explorer) surfaces.
