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)
You are just basing on bitcoins price potential rise up.Try to look at on difficulty and you will see that cloud mining investments will not give you give good payout even on $10000 price/BTC.Difficulty does matter not on the price most of the time unless if it would hit up ATH then we might see some good payouts but it doesnt mean it will reach you out Roi way more faster.
Smart investing is suggested but i dont see cloud mining will be included into that choice.
ahha) actually yes; however, who knows do we have this 10 years or not) people want to live good here and now)
Bank can't give you 100% profit in 10 years, who told you that? If you don't have 10 years don't think about any investing, simply if you don't have time for waiting your investment to reach it's full potential, take that money you planed to invest and spent them. If you have kids you will think about them, if not spent it on drugs and prostitution. If anything banks can be compared with cloud mining, both will eat your money, in one way or another, I believe that just holding 1 BTC for years will generate more profit than banks and cloud mining together, and guess what it's much safer in my opinion, I have more trust in bitcoin than in banks and cloud mining devices.
