Asides having money, it is always good to consider electricity too as that has been one of the major challenges most miners always have and once that is out of it, the rest is history. Bitcoin mining is good and can give more over time since you really would not have to be doing much and the miners are doing all the work. A lot is necessary to consider before mining which makes the knowledge come to play. However, I would not even bother myself delving into the cloud mining space as there is nothing there for anyone.
