Actually the cryptocurrency market is so complicated to understand and hard to predicted.
I can say it is feel like random market and even manipulateable , so the topic is wrong for me personally.
Yes when there will be more possibility of manipulations, I guess we cannot expect any specific patterns to happen all the times. I mean to say we cannot expect all the times bitcoin and altcoins to be get traded in opposite directions. Because there are occasions where few of altcoins that being traded in same directions and in some other occasions just the resiprocal was happening.
The prime reason for this must be insiders and their heavy manipulations. Random movements must be the right term to be called for these markets.
Insiders for cryptocurrency is unlikely. There are too many factors that go contribute to bitcoin price movements, unlike the stock market where someone can have access to quarterly reports ahead of the public. I'd be more scared of pump and dump groups manipulating the market.
