How do I purchase mining contract?
It is very simple. Once you have your account created new user menu will show once you are logged in. On top of the page click on "Buy a new contract" link. But for Deposit, minimum is 0.3 BTC and equivalent in other coins. We can't accept below it. Once you are on that page you can see your "deposit address", you should send BTC to this address and after 1 confirmation BTC will be available for you to buy new contracts or Cryptoion vouchers.
