Impermanent loss จาก Yield farming - มีหลักการง่ายๆ ไหม?

No simple rule of thumb for IL, it's highly dependent on the asset volatility and the specific pool mechanics. You just have to model it out for your chosen pair, or accept the risk.

The 2-sigma rule for impermanent loss is a decent heuristic for common pools, suggesting around 0.5% IL for a 10% price change. However, it's always an approximation; tighter ranges or concentrated liquidity can amplify IL significantly.

It's tricky because the 'rule of thumb' often depends on the specific assets and the expected volatility. For ETH-USDC, the IL can certainly sting if ETH makes big moves. Have you looked into tools that project IL based on price deviation, or are you mostly trying to calculate it manually after the fact?

This is a great question. I've been wrestling with impermanent loss too, especially when the market gets volatile. Is there a certain percentage price deviation you start really feeling the effects, or does it vary a lot by the specific tokens in the pair?

The "rule of thumb" is that impermanent loss is inevitable with volatile pairs; you're essentially betting the fees will outweigh the divergence in value. For ETH-USDC, you'll always have some exposure. Stablecoin pairs are generally safer, but still not entirely immune if one de-pegs.
