This wave of excitement in Meme, to put it simply, is everyone pricing based on emotion, with narratives changing suddenly, and the K-line being more fragile than people's hearts.

My own stop-loss is just one sentence: first, think clearly about "what am I actually buying," whether it's liquidity, hype, or just a gamble;
if the answer is hype, then don't pretend to be a long-term investor, set a price/time to exit, even if you sell at a loss, accept it.
Another very realistic point: fees and slippage can turn "stop-loss" into "cutting losses," especially during cross-chain or Layer 2 settlements, don't wait until you want to run and find you can't move.
I'm also tired of the macro discussions about rate cut expectations, the dollar index, and risk assets rising and falling together; when emotions are aligned, that's the most dangerous.
Anyway, I’d rather earn a little less than be the last one to hold onto faith.
