I definately see correlation in wave structure between 2013th bubble and a current. This is update of "Long termprice extrapolation" posted 7 Oct 2016.Many time past since then. And log scaled trends grew a lot.You can see some historical trends here. The lowest defines "Normal growth" and price is currently inside it. The upper ones defines "mid and super grow". Once price enters them it will start drammatical growth due deflationalnature.Corelations I see between 2013 and current bubbles marked by circles. So taking into account that correlations I announce drammatical price rise from approximately $40,000 USD in quick and pessimistic version to more than $100,000 USD and prolonged optimistic version.Deadline for this action is till 2019.
