The bonus program is available to all accounts. To participate in the bonus program you need to have hashes in your account. Your bonus amount will depend on the number of hashes you have. You do not need to sign up or opt in to the bonus program. Once you have the required number of hashes you will automatically be in the program. This is a bonus paid on mining income only. The bonus is based off of your own and your referrals mining earnings. This does not include any other earnings for the day. Bonus payouts are added to your account once per day.
