Our advantages
We notify your bitcoin miner about new block with the help of long polling. This allows to minimize the number of stale shares. (extra 0.5%-1.5%)
We pay you for every solved block, even if it later becomes invalid (0.5%-1.2% extra)
We provide e-mail notifications on worker failure
You can take your reward at ANY moment, just press "Instant payout" button
You can choose between two payment modes
Pay Per Share: You get a fixed amount for every share submitted. This method has zero variance but slightly higher fee (because pool takes the risk). Recommended if you like steady payouts.
Proportional: You get a portion of every solved block proportional to your part in pool's hashing power. This payment method has a noticeable variance: some days you can get less, some days you can get more. This is due to randomness of searching for proof-of-work.
We pay a competitive price:
Pay per share: 0.00000250716044609 BTC per every submitted share
Proportional: your part of every solved block less 3% fee
We credit your balance instantly, without 120 blocks delay
We have open and free registration and do not limit the number of connections or users
