I can't believe how many absolutely idiotic stupid morons are out there who keep believing in these mining shares. For starters, the math proves that you will never get your investment paid back, let alone any interest on that investment. Second of all, all of these operations would be stupid to actually mine bitcoin since it is so troublesome. They can make money by just taking your money and slowly giving you back little by little but never giving it all back. Why would they run a gigantic bitcoin farm when they can simply run a single server and not have any headaches? Also have any of these cloud mining companies actually shown any evidence that they actually mine bitcoin? I don't think so. All you ever hear from them is "trust us, we do!" What a load of BS. Some of these operations, if they truly mine bitcoin, would have gigantic mining farms, so why can't they give us any shred of evidence that it exists? There is not even any circumstantial evidence of their existence for most of the cloud mining companies.
Lastly, even if these companies were completely honorable and actually mining like they claim to, how freaking stupid do you have to be to buy into something that you will never profit from? The only people who make any sort of profit from cloud mining are the cloud mining companies running the ponzi scheme and some people who trade fake mining contracts with gullible fools.
