Guys please keep this in mind, from their TOS
3. The Exchange Service.
3.1. No exchange service for the US customers. We cannot offer our service to the US residents or anyone geographically located in the US. Accordingly any attempts to exchange cryptocurrency from a US based IP address will be blocked. We apologize for the inconvenience.
3.2. Transactions with HolyTransaction. When buying or selling cryptocurrency through the Exchange Service, you are buying from, or selling to, HolyTransaction directly. HolyTransaction does not act as an intermediary or marketplace between other buyers and sellers of cryptocurrency. The Exchange Service is subject to the HolyTransaction "Exchange Rate." "Exchange Rate" means the liquidity adjusted price of a given cryptocurrency amount in terms of currency or cryptocurrency as quoted on the HolyTransaction Site. For the purpose of any transaction which incorporates the Exchange Rate, you agree, as a condition of using any HolyTransaction Services, to accept the Exchange Rate as the sole conversion metric.
3.3. Cryptocurrency Exchange. Once you have successfully completed required verification steps, you may exchange among cryptocurrencies supported by HolyTransactoin (subject to applicable transaction limits). HolyTransaction will deduct specified amount of cryptocurrency that you are selling from your HolyTransaction Account. In most cases exchange transactions will be executed immediately. If HolyTransaction does not have requested funds available, it may take some time to execute transaction. Amount of time depends on transaction size. Once your cruptocurrency exchange reqest is submited with your HolyTransaction Account, such transaction cannot be cancelled, reversed or changed. HolyTransaction will use good faith efforts to fulfill any exchange request with the Exchange Rate quoted on the HolyTransaction website at the time of order placement.
What I find odd is that their contact info is based in the US?
