Interesting - and thorough! - reasoning. However... aside from puting all eggs in one basket, which is not the best strategy ever, I would remark that you didn't consider the penetration of cryptocoins among English and Russian speakers, respectively, but started from the idea that all of them will be investing in the respective coins at one point.
You definitely caught my attention, though!
Yes thats a fair point about me making the hypothesis that all of them will be investing in the respective coins at one point.
That is what I believe. Not ''all of them'' exactly, but I believe some language/geo/niche specific coins will be more appealing than lots of other cryptos that are trying to go for a broader market. Which is also why I'm confident in my Golos play. Like all cryptos it has significant downside risk, but I believe the ROI for it is much better than all other cryptos out there. And Golos is basically at the same price today it was in January 2017 - it hasn't been overbought like nearly all other alt coins. Thats why I went all in on it
