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?
Well there could have an effect but not won't hurt the entire bitcoin, a small percentage will be noticeable and it is easy to recognize when miners will not continue to mine. But this seems very impossible to happen, stop bothering yourself about this because it will never happen that Russia will shutdown internet, most people need internet from work and to their family --it is like it belongs now to the most important necessity is the internet.
However, I have read the news before that even radio waves bitcoin can make transactions and I don't think everyone wants to explore it.
They do plan on shutting it down to other nations, so connection to the world. Which means internet will keep on existing, but we will just not have Russians connecting to the rest of the world. Obviously they can easily use VPN and still connect, internet can't be limited and governments fail to see that in all around the world, you can even go online as a north Korean person. However, this will not impact crypto at all.
If you are in mining world, you are smart enough to know that you can keep on mining using a VPN connection, even would go satellite connection to some other ISP if you have to. Russians will figure it out and won't be a problem at all.
