I am yet to see altcoin that goes up when bitcoin and whole market of cryprocurrency is down. Most altcoin that temporarily rise when market is down are most likely been pumped or the excitement of new listing help the demand for such coin. Sooner or latter, every altcoin go down with the market sentiment! Bitcoin prices is important in determining the pace and growth of cryptocurrency, most altcoin are yet to decouples from it!
There could be some, but those are way below in the list from the cmc.
So it means they are purely being used for p&d that's why there are no relation to bitcoin regardless if the price is going up and down.
I'm not new in the market but not that old, but I've seen this kind of movements. But it doesn't concern me because I know there is someone from behind manipulating the price.
