  • The information on this page contains estimations based on hash rate measurements submitted by our users. Due to software and hardware glitches, some users submit exaggeratedly high or exaggeratedly low hash rates that don't correspond to reality. Thus, the estimations calculated for some video cards are either too high or too low.

  • Please don't make hardware purchase decisions based solely on this information, or disappointment may follow. Please do more comprehensive research before purchasing hardware, and confirm the hash rate and daily income from multiple sources.

  • Also, keep in mind that the crypto mining income may be highly variable because of multiple factors such as difficulty and exchange rate variation, mining algorithm changes that some coins do from time to time, and even pool luck.
