I have some low value tokens I earned from a game that I've been slowly converting to ETH over the last few months. Sometimes the gas fees are very low, like around $3 to convert $100 worth of tokens. Today I'm trying to convert about $85 worth, and the gas is about $25-$35 when I get a quote. Seems ridiculous to lose 1/3 of my crypto during a swap. I'll keep checking until I can get it for under $10, but what should I watch for to let me know when the time might be right?
