Yeah, we are shocked in Russia too, what the actual duck is that. A lot of people used BTC-e to deposit money and then send it to trade on other trading platforms.
If you have more than 10 BTC of cryptos in your portfolio, I'd highly recommend keeping money in your private wallet. Only then send it to trade and back to the wallet with profits. I'd also recommend putting some profits in a bank account (If you've already doubled the amount of money invested, just to be safe).
