It was run on a .ru domain years ago, and I believe the exchange was based in Russia at that time. It was banned by the Russian government, and supposedly the exchange moved operations to Bulgaria and/or Cyprus. The .com domain was eventually also banned by Russia, so they mostly use the .nz domain. That domain has yet to be seized.
I didn't verify for myself, but I saw someone post earlier that btc-e.top was showing a mirror of the old site. They said the domain was registered to the same company as btc-e.nz .... VERY interesting if so. Apparently btc-e.top was also redirecting to Exmo (a Russian exchange with alleged ties to BTC-e). I wish I could find that thread now....
This whole thing is one big joke. Steal everyone's money because one person tried to run a big scam. Why not give everyone a chance to withdraw and THEN proceed with legal stuff? You can't just take billions of dollars from people because of one guy.
Unfortunately, asset forfeiture law/regulations in the US were written precisely so that US law enforcement agencies could seize money without proving guilt. It's a shakedown racquet. Even if you are innocent, the costs of mounting a legal defense against asset forfeiture are often not worth it. That's why the practice has become so rampant.
Sadly, the US government can take billions of dollars from people because of one guy. Nobody can stop them.
This case is still up in the air, though. BTC-e made an announcement yesterday that they were able to access their wallets and are evaluating the damage. They also said that fiat money held by Mayzus has been frozen. In both cases, it is not clear what amounts have been lost, and whether the exchange is technically solvent:
Current information:
1. We were able to access our databases and wallets, at the moment we are evaluating data and balances on koin, this information will be made public by the end of next week.
2. We confirm that the main streams of the threads have been sent to the service through Mayzus Financial Services Ltd and at the moment they are arrested.
Best regards support btc-e
