How much profit Mr. Z can generate using cloud mining if we take into account this price you offered: $ 20,000 ? I mean If he supposedly bought for $6400 and then invested when price was already much higher. I guess If you invest at the time of high price you still able to generate good profit. However, you can't be sure that price will not drop again, that's true. I think you should have this feeling...and invest smartly at good timing and withdraw in time as well. Which is hard obviously)

I thought to purchase my own equipment but it turned out to be not so easy and very costly. Cloud mining gives us good opportunity to earn by investing not so much. At least it gave before... So I keep waiting for industry to recover.
