Considering Russia household income per capita, IMO it's rather high.
It's high even in majority of the European Union, based on min wage values, so yeah, at face value, certainly doesn't seem unreasonable to tax such a high limit for the average Russian -- and if that's per exchange, nothing to stop people from using several exchanges to break amounts up.
Minimum wage isn't best indicator for comparison, but i agree it's relative high even on EU. They also could split it between family member.
Everyone that says Russia is not going to invade the Ukraine, must take note of this move ...because it is a backdoor that are being opened to evade strict sanctions when they actually go ahead with the invasion.
They could use Yuan to evade sanction though, especially when media recently report good relationship between China and Russia.
