First-block predators: snipers, bundlers, MEV

You saw the launch tweet, clicked fast, and got in "early." Cute. The first block of a memecoin launch is not a starting line — it's an aquarium of specialized predators that were done eating before your transaction was even built. Snipers are bots that watch for pool creation on-chain and fire buys in the same instant, often paying priority fees you wouldn't pay for a used car. By the time a human sees a chart, the sniper's entry is the floor you're buying above — and your buy is the exit pump they were waiting for.

Bundlers are the house playing at your table. On Solana launches, a deployer can bundle the pool creation AND a spray of buys from dozens of their own wallets into one atomic transaction — the token launches pre-bought by its own creator, disguised as organic demand. The holders page shows 40 "different" early wallets; they're one guy in a trench coat, waiting to feed his bags to the crowd. Bubble-map tools that cluster wallets by funding source exist precisely to catch this. Then there's MEV: because pending transactions can be observed and ordered for profit, a sandwich bot can shove a buy in front of yours (raising your fill price), let your slippage tolerance eat the difference, and sell right behind you — a tax on being visible.

The defensive posture: assume that in any fresh launch, the first block belongs to machines and insiders, and the "early community" you're joining at minute five includes the people planning to sell to you at minute six. Check bubble maps for bundled supply. Check what percentage the top wallets control and when they bought. Keep slippage tight so sandwiches starve. Use RPCs or aggregators with MEV protection where available. And internalize the ugly default: a fresh launch's economics are usually a queue, and retail joins the queue at the back. You are not early. You are the demand the early people ordered.
