The article is inaccurate, unless the law on paper and the actually applied rules are different.
Regarding the mandatory 80% sale of foreign-currency income, on paper, it does not apply to the income earned before 2022-01-01. So the majority of my EUR balance is still in my account.]
The ban for making bank transfers outside Russia, on paper, applies only to transfers to one's own accounts abroad. There are reports that SWIFT transfers from non-sanctioned banks to accounts held by others still work - but I haven't tested this. Heh, it might be a good time to buy a small villa abroad while this is still legal ;)
