BTC-e is banned in Russia, like most Bitcoin exchanges. Russians cannot access the .com domain, which is why they used the .nz domain. In fact, BTC-e was originally hosted on a .ru domain; they changed to .com (and supposedly moved operations to Bulgaria) when the Russian government targeted them.
Insiders like Penek and several people over the years who have suggested they know the owners' identities from the launching days of the site have suggested they are Russian. (This was in the context of whether Vinnik was an owner and whether the owners ever would have set foot in Greece -- the answer to both questions is no).
WTF are you talking about?
MaRSe is a huge Bitcoin exchange right in the heart of Moscow!
Huge? I've never heard of them and can't find them listed on Coin Market Cap. What sort of volume do they do?
The Russian government has banned dozens of bitcoin exchanges over the years. Google it. The Prosecutor General's Office even stated that their use was prohibited under Article 27, saying that bitcoin is a money substitute in 2014. There was a fresh list of sites banned shortly before BTC-e was taken down. Can't find it right now because of all the more notable recent news results.
That's just when it was last registered. This would have been years prior to that. They were on both .com and .ru back in 2012. Here's one example of a user using the Russian domain to access the API in 2012: https://bitcointalksearch.org/topic/need-help-with-btc-e-api-133347
Both domains were blocked by the Russian government. Why do you think all Russians customers used BTC-e.nz for years?
I don't think anyone is saying otherwise in this thread...
