The payment for the Challenge should be done by Bitcoin. All Bitcoin transactions are processed on the Blockchain network. The network or your Bitcoin Wallet Provider may charge fees. Make sure you consider these fees when submitting your entry fee for the Challenge.



In the case that we will not receive the full amount from you, further instructions will be sent to you via email automatically. Check your Spam/Junk folders to find that email.
