Is Hadron accepting also new miners lately? When will the system be open to everyone with no limits or will there always be echelon levels for the miners?
Hadron is accepting new miners for the beta test.
The beta test might have something similar to the alpha test.
The alpha test will last for 2-3 more months and then the beta commences. The completion of beta test is determined how the testing/dev process goes. It is after the beta test when the system will be open for all to mine.
