Another factor could be the political climate in Russia and maybe the uncertainty towards crypto adoption. Russia is the kind of country that wakes up and bans whatever they want.
This could be the main reason. This makes much more sense. I know some Russian friends who don't like to be there and want to move to another country. But they couldn't. One of the main reasons is, that they have to abandon their house and the money they have. They said that they won't be able to keep their money with them. I don't know why it's too difficult when we have cryptocurrency. Some people live in Russia, but they don't like to be there.
A company may want to avoid any kind of possible future problems like a Mining ban, crypto ban, or Bitcoin ban. But I guess they have to pay fees as well for investing outside of the country.
