I really want to know which alt you mean because I believe most altcoins will follow the bitcoin price trend so far. IMO, the current average of the top altcoins have fallen by more than 80% since their last ATH, I can expand the list here for comparison.
You got it right, bro. I really wonder what altcoins OP was looking at that really didn't "dump" except for stablecoins or coins that are pegged to things like Gold. Hell! Even all "stablecoins" are more than -10% from their "all-time high"
