Russia is considering shutting down the internet connection to the rest of the globe. What will occur? Is the hash rate decreasing? What will happen if the connection is re-established in a few years?
As per the latest data Russia has almost 12% contribution towards the hash rate of the total globe. Only if you include Kazakhasthan it reaches upto about 30%. So if Russia blocks the internet then I don't see a very drastic effect of it on the Hash rate, just a 12-15% drop. If you want to take reference I would rather recommend see China, it had almost 50% contribution in the mining hash rate before China completely banned bitcoin mining from its territory even after that since then I have seen hash rate rapidly increasing instead of falling down. This might have owed to the price increase since then. Therefore I am sure Russia block access won't be a major issue for the world.
