It’s a mining co-op. For a free account they pay out $1-$2 per day in Bitcoin for 100 days. Just create an account. You can purchase upgrades of course but it’s not required to get the free bitcoin. So every day, it is going to mine bitcoin for you. You can collect it and send it to your bit coin wallet.
They also have upgrades that you can purchase if you want to increase how much the workers produce daily. The season runs for 100 days. Do this even if you do nothing at all, you will collect $100-$200 in bitcoin just from the free account. Share your affiliate link to get clicks that can be used to upgrade and acquire note workers also. That's IF you want to do that. Again, it’s not required for the free daily part.
