I don't think it's fair to compare cloud and hardware. I think it would be more of the prisma against SP20. And really amhash is not cloud but a havlock investment.
Of course AMHash is a cloud mining service. Using Havelock doesn't change the fact that you get x Gh/s for y BTC does it? Anyone treating AMHash like an investment instead of the mining contract is a fool given that it's guaranteed to drop in price as network hash rate increases.
As for comparing AMHash to other miners, why is that not fair? You're buying hashing power either way, only mining contracts are cheaper and therefore more profitable and that's the real reason why most people buy miners - profit.
i suppose what it really boils down to is personal preference.
some people are willing to trust their funds in the hands of others with IPO's and what-not and some just enjoy to mine.
I think you are right, amhash is not a real mining operation - it's a smoke and mirrors way of Am getting suckers to invest (again)
i've been away a while so forgive my ignorance, but... have AM yet paid out their shareholders from their last 'IPO' ?
AM have only had 1 IPO so I don't know what you're talking about. And people who bought AM at IPO and are still holding have made 600% profit from dividends. How is that relevant to this discussion though? It isn't. You're just trying to divert attention because you have no valid response to the fact that SP20's are vastly overpriced compared to the competition.
What is relevant is that the mining contracts being advertised in my signature are vastly better value than the miner being advertised in your signature and AMHash offers a far greater chance of making a profit from mining bitcoins.
You'd probably make a lot more money if you changed your affiliate link to advertise SP35's or something that isn't insanely overpriced.
you need to do some catching up!
feel free to stick your 'maintenance cost' - somewhere in China.
my SP10's are still running away quite happily
