I believe those who were aware of cryptocurrency and had account on Kraken are far away from war zone (or have travelled abroad) and can use white or grey methods to turn crypto into cash.
What do you base your assumption on?
I believe that those, who are on war zone territory right now, only heard what is crypto. Many Ukrainians who not only aware of cryptocurrencies, but also use them, invest in them and even create new tokens, have remained in Ukraine and are now in the midst of war zone. There is no correlation between their awareness and going abroad or far away from the war.
Imho, people who had knowledge what is crypto and had exchange accounts, are average class, has money (at least emergency money) to move out quickly from Ukraine. They will find access to the internet and will withdraw that gift from Kraken.
Having money and crypto doesn`t imply that you will leave your country, which was attacked by troops of another state. Many of our people have joined the army or territorial defense and are now defending the homeland. Moreover, men of military age cannot leave Ukraine now. So how can you say that people who had knowledge what is crypto and had exchange accounts, are average class, has money (at least emergency money) are moving out quickly from Ukraine?
Low level class people are left in war zone, people who find it impossible to leave their property, relatives and etc. Sorry, but their maximum is having a bank account and only hearing about "the internet money" aka crypto.
Again, why did you decide that only people, who don`t have money, remained there? Besides that, in Ukraine quite a lot of people not only heard but also bought cryptocurrency. The problem of saving money was very relevant for us even before the war. That's why our people are creative in finding new ways to save their money. And now most of these people are staying in Ukraine.
