Money disappeared; at first, the exchange wouldn't allow conversions, then there were problems buying BTC—technical failures, and as a result, my account was left with zeros, while customer support couldn't help at all. That's the situation with the Belarusian exchange. Fortunately, there was only a small amount in the account, so it's not as painful. Usually, you start with small investments to avoid stressing too much over losses, but it's still unpleasant.
