Crypto adoption - not really, cash is king. No one is going to suddenly switch to a completely different and unstable currency when the current currency is still working well.
I don't know anyone who carries large amounts of cash on them. Banks are often closed during wars and times of crisis, which can make it difficult to withdraw cash. Looting, violence and crime also rise during war and times of crisis. Cash carried in a wallet or pocket can be taken. Or confiscated by soldiers and security forces.
Crypto by contrast cannot be taken as easily. It provides an additional feature of making it easier to receive money and donations. Kraken exchange was offered $1,000 in funds to every person in ukraine who had made an account before the crisis began. There are other crypto projects aimed at donating funds to refugees in ukraine via
BTC and other tokens.
But what really opened the door to crypto adoption in ukraine were services like paypal and electronic banking being shut down intermittently. Crypto was demonstrated to have the better realiability and uptime in contrast to trusted brand name services.
Satellite Internet - when Russian occupants enter a village or town, one of the first things they do is destroying or jamming local mobile networks. Similar things can be done to musk's starlink dishes. They also can't survive the shelling that often target residential areas.
Every single time there's a crisis in the world, someone will say "this is good for Bitcoin", and yet practice shows that the use of Bitcoin in such situations is just some lone cases rather than a trend.
Mobile networks can be used to fly drones, which can be used to attack the russian military. In that context, they can be a target.
Another thing that happens when countries like russia invade is them conducting electronic warfare against the national internet backbone to jam communications. In which case, satellite internet is the only remaining option.
Satellite networks don't need to transmit 24/7. They can be used when needed and shut down when they're not. If they're being used to buy a cup of coffee and for relatively innocent and non military purposes, russia won't care.
Its satellite communications used by the ukraine military to organize and to conduct drone attacks, that russia is concerned with.
Its not a question of whether its good or bad for crypto, it has more to do with demonstrating real world value that crypto can have to ordinary people in times of crisis. Bitcoin can literally save your life. Surely this must be worth something to someone.
