IMO the most legit is Cex.io
That's why it is
less profitable
The most profitable now is something like hashprofit. I almost sure it is hyip, but it pays now and will pay some time more.
Did u say less profitable ? From when -ve earning is less profitable ? It is simply loss.
Yes, you are right:) You cannot earn money using their mining.
But you still have two ways to receive some profit from cex.io:
- attracting referrals
- selling your ghs at a higher price than they were bought.
