My current approach to meme/narrative is pretty soft: if I can make money, I take it; if I lose, I accept it. I set a hard stop-loss upfront, otherwise when things get lively, I easily fall into the trap of "I'll wait a bit longer."

Honestly, I only have two rules: first, before entering, think about the worst-case loss you can tolerate, and cut it immediately when that point is reached—don't tell yourself stories; second, if the price is rising too smoothly, sell some in batches and keep a little as a lottery ticket. Recently, isn't there a bunch of new L1/L2 projects offering incentives to pull TVL? Longtime users complain that "mining, token selling" isn't without reason... When incentives stop, enthusiasm dissipates quickly, and emotions move faster than the chain. Anyway, I’d rather take a smaller loss now than be the last mood-maker in the group.
