These servers hold the data of your coins and $, so I wouldn't call it nothing.
They follow Cypress laws. They aren't Russian company. Why Russia could seize their servers in Bulgaria?
Maybe Russia would seize MtGox servers in Japan? Or Bitstamp's in Slovenia? All exchanges will fire because of Russian govt! We all will die! PANIC! SELL SELL SELL!!!11
The USA seized servers and arrested Kim DotCom in New Zealand. Even using FBI hardware and officers to do so.
The USA gets UK citizens extradited for breaking US law, despite the fact that the citizen never broke any UK laws.
Powerful countries have leverage over less powerful countries, especially when any kind of trading links are involved.
If Russia is serious about nailing BTC-E for whatever reason, and it leans on Bulgaria to any degree whatsoever, these servers are getting switched off. Simple as that.
Russia is not USA.
Yes, I know, you probably have a short position, but no, Russia is not USA and actually has no power to seize something outside.
The main thing Russian govt cares about is foreign money that could sponsor the Russian political opposition. Nothing more.
They are just trying to close any pipes of foreign money.
So, the most "scary" event that can happen is possible ban of access to the BTC-E website in Russia. Hello Tor & VPN!
