Your calculations do make sense in terms of Golos being way undervalued compared with Steemit (39x less today). Given that Golos is basically the same as Steemit but for Russians, it stands to reason that the price differentiation should be more like 4x as you say. I'm intrigued.
Whats an example of a Youtube channel pointing people in the direction of Steemit that you mentioned?
For example this Youtube channel

I've seen other channels too, its a trend. Its helping Steemit and Golos grow in traction
