One more thing to add:
- Typically, pools are: MEME token-SOL/USDC, but the Dev only adds MEME tokens to the pool without adding SOL/USDC. If you encounter this kind of Dev, run away quickly.

Benefits of knowing the range:
- LP exceeding the range means there's no liquidity above/below. This leads to increased slippage and higher transaction costs.
- Some whales can sell off by forming LPs; you can understand the intentions of major players through the LP range.

Watch out for devs who only add MEME tokens to the pool without SOL/USDC. Low liquidity can lead to high slippage.
