I agree, the desktop mining being possible is what I heard. But I could never login as well to download 'electroneum miner' to my PC as it was only available after logging in. Maybe it was available for a short time, but my guess was that folks part of the team or connected with them were able to access the miner to start the mining process as part of testing work and they were selling the coins in Cryptopia. However [-]piesarkin says anyone can mine, so maybe it is true. I will let him clarify further
