Right now I would say there's a lot of bitcoin being sold or traded for other altcoins. Interest in ETH is huge and people are looking for the next bitcoin or anything even close to that.
Ethereum is just fueled by hype as of now. It will die with all thee pumping it was having early on but will vaporize soon. Bitcoin will be left the victor on this front. Just look at Litecoin, do people even use it anymore other than trading it for bitcoin. Come one now. Reality is nice, isn't it?
The price of Bitcoin is now stable, and people wants to make some profit now around this time, so they are now going to trade so they can earn a little bit money with it.
And that is quite good and that give you also distraction to wait such a long time for a price increase, I heard from some people that it will take a really long time until it have a high value.
