This is my observation or am I dreaming!
Usually price hikes in Bitcoin have MORE positive price movements in ALTs: This time it is not playing out like that. This could have a negative impact on the Bitcoin price!
I could say more but I will leave it at that!
You are right, i have noticed it too.
But this is regarding the small alts, some of the big altcoin are jumiping high.
This is a interesting maret situation , one possible explanation could be that BTC price is manipulated thus the other alts does not see the influx of money and stay relativly stable.
