NiceHash is a hashrate marketplace. Which means it works on demand and supply principles. Because of that, NiceHash can pay more than mining directly.
If there is a high influx of supply (additional hashing power), the demand side cannot adjust fast enough and the price of the orders will likely drop. This will cause a short-term profitability drop for all the miners until the buyers can adjust their prices.
We suggest slowly connecting your workers to the NiceHash stratum. This will prevent the price on the marketplace to drop too fast which will be beneficial for buyers, but not miners - yourself. Try to connect around 10% of the total NiceHash hashing power on the algorithm every day or two.
For example, if a SHA256 marketplace has 300 PH/s, then we suggest connecting around 30 PH/s per day or two. You can find the current total hashrate here.
NOTE: We use the second SHA256 marketplace for the AsicBoost protocol. Connect your SHA256 ASICs to the SHA256AsicBoost stratum instead.
We offer white-glove support to mining farms with 100 or more workers. Please write to farm@nicehash.com if you have any additional questions.
