Like I have said earlier during last 6 or so months focus has shifted from Bitcoin and Ethereum to Litecoin and Dogecoin... That means demand of Bitcoin has dropped.
One of the reasons is sharp decrease in number of altcoins and value of some of the remaining altcoins dropping to sub-satoshi levels.
The other big reason is that people don't need to swap their FIAT to Bitcoin first anymore as services like Coinbase support other coins too... People save a lot when they don't have to pay large network fees commonly associated with Bitcoin.
