Sniper Bags Exposed: How the First Block Sets Your Stop Loss

The First Block Is the Trap

Every memecoin launch has a first block. That block contains transactions from sniper bots — automated wallets that buy the token before any human can click a button. These bots are not traders. They are extractors. Their goal is to sell into your buy order at a higher price, often within the same minute.

If you do not understand how sniper bags work, you are trading blind. This lesson breaks down the mechanics, the signals, and the only tool you need to see the setup before you buy.

How Sniper Bags Are Created

A sniper bot monitors the mempool for the creation of a new liquidity pool. The moment the transaction that creates the pool is confirmed, the bot submits a buy transaction in the same block. This gives it a position at the very bottom of the supply curve — often at a price that is 10-100x lower than what you will pay in the next few seconds.

Key facts about sniper bags:

• They are usually spread across 5-20 wallets to avoid looking like a single whale.
• The total percentage of supply held by these wallets is often 5-15%.
• They never hold long. The sell order is queued before the buy is even confirmed.

The dump is not random. It is engineered.

The Two-Phase Dump

Sniper bots do not sell all at once. That would crash the price to zero and leave them with nothing. Instead, they execute a two-phase dump:

Phase 1: The initial sell wall

Within 30-60 seconds of launch, the bot places a sell order at a price 2-5x the launch price. This wall catches early buyers who are chasing green candles. The bot sells a portion of its bag here, taking profit while the chart looks healthy.

Phase 2: The trailing dump

After the initial sell, the bot watches the price. If new buyers push the price higher, it sells more. If the price drops, it sells into the panic. The bot continues until its bag is empty or the liquidity is drained.

By the time you see a "dip" and think about buying the discount, the sniper is already gone. Your entry is their exit.

How to Spot Sniper Bags Before You Buy

You need to check the first block distribution before you enter any position. This is not optional. On GMGN, you can view the top holders for any token and filter by "first buy" or "first block." Look for these red flags:

• Multiple wallets that bought within the first two blocks and hold 1-3% each.
• Wallets that bought with near-identical gas prices or amounts.
• Wallets that have never traded any other token (fresh wallets).

If you see 5+ wallets that all bought in block 1 and hold similar percentages, you are looking at a sniper cluster. The price will dump when they sell.

The Only Safe Play

There is no safe play against sniper bags. You are buying into their exit liquidity. The best you can do is:

• Skip the first 5 minutes. Let the sniper sell happen. If the token survives, you can buy at a lower price with less risk.
• Set your stop loss below the sniper cost basis. If you can estimate their entry price (usually the launch price), set your stop just under that. If the price breaks below, the bot is dumping and you should exit.
• Never buy tokens with high first-block concentration. If 10%+ of supply is held by first-block wallets, the token is a ticking time bomb.

The Hard Truth

Most memecoins go to zero. Sniper bags are one of the main reasons. The people who make money are not the ones who buy early — they are the ones who sell into the early buyers. You are the exit liquidity unless you learn to read the first block.

Do not chase the green candle. Check the distribution first. On GMGN, you can see exactly who bought first and how much they hold. That information is free. Ignoring it is expensive.

Final rule: If you cannot explain where the sniper bags are, you do not understand the trade. Do not buy.
