Why do you keep hearing mining is unprofitable? Because, mining really is unprofitable, when you take electricity costs and increasing difficulty into consideration.
Another sockpuppet that doesn't understand math...
Hi, I am new here. Could you take some time to explain that?
I have read quite a lot of posts here, and many of them mentioned the mining revenue will drop 20-30% every 2 weeks. If that's the case, it seems all of the mining equipment I found on the net cannot earn itself back. I have also use some online calculator and find that the cex.io cloud hashing cannot earn itself back as well.
