GMGN URL: https://gmgn.ai/ Use GMGN indicators to advance the screening of Meme coins. In the introductory chapter, we have analyzed the idea of ​​scanning chains and judging potential Meme coins. Specifically, we should base on hot topics, narrative, market value, community and Market dynamics determine whether to buy. So how to quickly scan chains and screen safe tokens on the GMGN token dashboard from an indicator perspective? Pay attention to the "Sniping New Coins" section in the lower left corner of GMGN. After discovering new tokens, click to enter the token trading interface for detailed analysis. First, look at a few indicators in the lower right corner: Liquidity pool size: Ideally, the liquidity pool should be above 100 SOL. Although it is possible to participate with a value smaller than this (such as dozens of SOLs), the risk is higher because it is easily affected by large players' selling. However, we should also be wary of some scammers using large pools to mislead users. Number of real transactions: Observe the number of real transactions after the market opens. If the number of transactions exceeds 60 within 1 minute, or exceeds 600 within 5 minutes, the token is relatively safe. Make sure these transactions are genuine and not a wash. Mint Permission Disposal: If the project team has discarded the permission to issue additional tokens, it is relatively safe. This means that they cannot issue additional tokens at will, thereby reducing the risk of market crashes. Blacklist: Confirm whether the project team has the right to blacklist any wallet.If "No", it is relatively safe; if "Yes", it may be risky because it means that some users may be restricted from selling tokens. Burning pool: Check whether the liquidity pool (LP) has been burned. The higher the burn ratio means that the project team cannot withdraw liquidity and the risk is lower. 100% burning means that the project team cannot withdraw the funds, which is the highest security. If LP is not burned, there is about a 60% chance that a “rug pull” will occur (that is, the developer suddenly withdraws funds). This step is key to judging the safety of the project. Top10 holdings: Observe whether the total holdings of the top 10 currency holders are less than 30% of the total supply. If so, it means that the holdings of tokens are dispersed, reducing the risk of a single large investor manipulating the market. Secondly, look at the position indicators below the middle K line: Monitor rat positions: Observe whether there is a rat position phenomenon. The lower the ratio of rat positions, the better. A high ratio may indicate that the project is manipulating the market, increasing investment risks. It is recommended that the ratio of rat barns does not exceed 20%. It is usually a more ideal situation if there are no rat barns at all. Finally, check the indicators above including social media and snipers: Analyze sniping by large players: If large players intervene quickly at the opening, and the depth of the liquidity pool is shallow, there is a 90% chance that the price will rise. plunge, so caution is required. Through the above indicators, you can more effectively screen out Meme coins that are safe and have investment potential, reduce risks and increase the success rate.
