I think you're a bit confused here Bitcoins and Blockchain going mainstream are two different things. People may adapt to blockchain ans yet not adopt bitcoins. So it's important to understand the difference here. It's true many companies are going after blockchain but not bitcoins but I feel this'll change sooner people and countries soon will go after bitcoins it's only a matter of time now.
Why not, it's not impossible that this year crypto goes mainstream,And I think many people having research and learning about crypto and in fact many investors now eying to invest in cryptocurrency.I believe and hoping crypto will live long last in the market.
