Use your browser to passively mine bitcoin and receive mining rewards instantly to your FreeBitco.in account, credited every hour.
Click on START MINING and then adjust the number of threads and CPU percentage to use for mining. Usually the higher the number of threads and CPU capacity that you use, the greater your mining rewards will be. The default is to start with as many threads as the number of CPU cores that your device has and 100% CPU usage. Lower the CPU usage when you are using the device for something else and increase it to 100% when your device is idle.
Mining will stop when the STOP MINING button is clicked or this browser tab is closed. You can use your account to mine from multiple devices at the same time. Mining rewards are automatically credited to your account for every satoshi that you earn and the TOTAL MINING INCOME in this page shows the total rewards that you have received from mining since the beginning.
