I am not comparing to bitcoin, I'm comparing to big altcoins.

If you want to compare to bitcoin you should head on compare. GRC overperformed during december and did worse during the crash. You can't only look at the shape you have to look at the difference.

So... ¿can I draw the same lines on BTC and get the same conclusion?
Sorry but I don´t see it. I am not an investor or trader... But I see correlations everywhere between coins, big or small.

Then you have some learning to do ;-)

From you? LOL
