1. We do not have a promo code of more than $100 on our exchange. 2. We do run a promotional Twitter campaign priced at $2 million. 3. we are not an ordinary exchange, but an offshore company of several projects. Therefore, the information about us on the web is minimal. We value the privacy of our users more than the promotion of the exchange. 4. The deposit we require is really big for some, for others it's pennies. 5. To withdraw your funds we ask for activation of premium account because we can not explain the origin of large amounts of funds in a short period of time, but our security service has not found anything suspicious. A premium account is a guarantee for us.

We do have problems with indexation, which we are addressing. And we are not promising any huge sums.

Due to a recent attack on our servers and a change of host, our website is no longer indexed by search engines, so it is not visible. We will solve this problem as soon as possible.
