Bitcoin Price Prediction --- 1 BTC = $57000 by 2020

It is widely known that Bitcoin [1] attains much of its value from digital scarcity. It has some properties of digital cash/currency and some of digital Gold. Only 21 Million coins will ever be created and many coins private keys have been lost forever.

Given the market capitalization of global fiat currencies is approximately $5 Trillion and the Gold market is around $7 Trillion [2]. It seems perfectly feasible that Bitcoin could attain 10% of this asset pool, which would equate to a market cap of around $1.2 Trillion. If this were to be achieved, the value of 1 BTC would equal.... 1.2 Trillion / 21 Million = Roughly $57000.
