Switzerland has taken a firm position against Russians possessing cryptocurrencies within its borders, and has announced that those assets would be frozen.
Following President Putin's war, the traditionally neutral country has joined the EU and the US in implementing financial sanctions against Russians. Furthermore, the Swiss authorities have pursued their cryptocurrency holdings within the country's boundaries.

Since Putin launched his "special military operation" against Ukraine, which developed into a full-fledged war, NATO and the EU have imposed severe restrictions on the country's wealthiest individuals (oligarchs) accessing banking institutions and even their own money.
It's worth noting that cryptocurrencies have been thrown into the mix, with watchdogs claiming that billionaires can use them to circumvent sanctions. What lies ahead is truly going to cause worldwide effects in the blockchain.
