Yes, it might also happen because if we look at the post-Russian invasion of Ukraine, currently the US has imposed several sanctions against the country, one of which is economic sanctions and recently Russia has also received sanctions against soccer competitions under the auspices of FIFA and UEFA, so I think it is not impossible that some of the largest cryptocurrency exchanges in the world will also block Russian users' IPs if the invasion of Ukraine continues.
If Russia uses Bitcoin, it will trigger USA and other countries in Europe to be against Bitcoin. It won't be good for the future of Bitcoin, USA and many other countries may ban Bitcoin and other cryptocurrencies because they are used by Russia to recover their economic sector. I don't expect Bitcoin will have an end soon because of this war.
