Observations from reading https://think.ing.com/uploads/reports/ING_International_Survey_Mobile_Banking_2018.pdf
1) "Fewer than one in 10 in Europe (9%) at the time of the survey indicate owning cryptocurrency ... One in four (25%) in Europe indicate they expect to own cryptocurrency at some time in the future"
So at a time when ~18% of Bitcoin remains to be mined, we see demand expected to triple. Works for me.
2) "We find that only about a third (35%) in Europe agree Bitcoin is the future of spending online. A similar share (32%) of respondents agree cryptocurrency is the future of investing."
Only? A third of everybody thinks that Bitcoin "is the future" of both spending online and of investing. And how big are these total addressable markets again? Thought so. I can certainly live with that.
...gotta wear shades.
