So if lets say a simple a class microhip (thats used in phones pci cards dvd players etc) ok its NOT a miner asic it cant do GH/s on one chip but it can put out lets say 90 Mh/s on its own and costs lik 10$ or much lower (if you order in big quantities) consider ordering 250 of them (= 2500$ -if we dont count the discount caused by the wholesale type of order- running at ~25GH/s)
that means that after 12 months you will have 3000 usd networth = 500 usd profit
But if there are some chips that do even better MH rates and/or you capitol is bigger then its totaly worth it.
No, it's not worth it. You'd lose a ton doing this.
If you were right, buying my ASICMINER blade at $500 would be a steal. After all, it does over 10GH/s. You're suggesting that 90MH/s at $7 is a deal. If so, 10GH/s (over a hundred times more) should be a steal at $500. So why are there ASICMINER blades not selling for even $400?
https://www.bitmit.net/en/item/59882-10x-new-asicminer-blade-10-7ghash-lowest-price-on-bitmitLook, that's 320 real ASICs, honest to goodness 100% optimized for Bitcoin hashing, more efficient than any general-purpose CPU, GPU, or DSP, fully hooked up and ready to mine for just $3,100 or so.
What you're missing is one very, very simple fact -- only the very latest generation of ASICs are profitable. Anything less than the very best costs more to power than you can make on mining and wouldn't make a profit even if you got it for free.
I have an ASICMINER blade behind me. I just recently shut it off because it costs more to power it than it makes in mining. It has 32 honest-to-goodness ASICs, fully optimized for Bitcoin mining. They're just not the very latest technology, and so even though I've already paid for them and already have them, I can't make money on them. If you're right, put your money where your mouth is. Offer me $400 for my 32-ASIC blade -- it hashes at 13GH/s on a paltry 135W. You can't get anywhere near that with any general purpose hardware.
