The Stratum pool for SHA256 and Scrypt must use extranonce2 size 4 or higher. The minimum pool difficulty must be respected, or the mining will not work.
If you are unsure if the chosen pool is compatible, use our Pool Verifier.
Choose a stable working pool! Unstable pools often go into a dead state, thereby giving you no hashrate.
Pool deaths and order cancellations are penalized with 10 seconds of mining. The miners working on that order are penalized.
Rapid work changes are penalized due to the miners' reduction in performance.
The speed limitation on the order is only approximate. See here for more details.
Duration is only approximate because hashing speeds can vary.
It may take several minutes before your order reaches the desired speed.
If your pool is unstable, you will not achieve the desired speed.
If you select a pool for the wrong algorithm, you must still pay for the shares miners submit.
If you cancel the order, the remaining Bitcoins and the remaining service fee are refunded, which may take up to one minute.
Use the edit function if you wish to only change the order price or speed limit. Editing orders is completely free.
Your order may appear dead at submit time, and it takes up to one minute for it to become alive (pool verification process).
The system may auto-cancel orders that are inactive for a long period (due to a very low price) or mostly dead (placeholder orders).
By submitting this order, you agree to the no-refund policy. Shares being rewarded to miners are non-refundable.
You cannot place an order to mine on NiceHash. Choose a high difficulty pool. Choosing an excessively low difficulty will result in a dead order, and penalties will be paid to miners.
