Futures contracts for Bitcoin starting in December 2017, hedge funds planning on starting to get direct exposure to Bitcoin in 2018, possible Bitcoin ETFs approval so regular investors can buy Bitcoin through an ETF, the most popular mobile payments app Square just started Bitcoin integration trials yesterday and its competitors are sure to follow in 2018. And of course organic user adoption will continue to grow on its own. More nations will figure out regulations for Bitcoin, thereby formalizing Bitcoins acceptance in the legal structure, even if they do not outright recognize it as a legal currency as Japan has done. Expect a price of anywhere from $25k - $40k.
