$9.49 per ghs? Lol. That will not ROI based on current exchange and projected difficulty increase by feb 15, IMHO. http://www.bitcoinx.com/profit/

Takes a lifetime to build a reputation and ten minutes to trash it. Mr Abiodun, that is a name I shall forever remember to stay away from, speaking for myself of course.

Ok, so where the you buy yours and for how much? BFL and these guys seem to be offering the best out there. I'm a newbie, and thought the best thing out is CEX, but that is nothing but a casino where the unacquainted get ra ped for ghs.

I want to spread my risk, hence why I ask. Hashfast was looking good till I heard they are in troubled with the law.

It's one thing to point out what is expensive, help us all out and point to the 'cheap' providers (and reputable of course, I got burned by an offer that was too goo to be true..it wasn't true)

Hope so. I'm new to it. Prices not worth it, but great way to make quick extra cash .
Like a casino with a relatively good chance of success if you're not greedy

That's strange. They were vetted by the nyt.
We don't have to scream 'scam' every time we have a bad experience with bitcoin. I am new to it and have been burnt once already by a new provider. Screaming scam doesn't help us in our goal as a 'community' - helping bitcoin gain traction with the mainstream.

Any step-by-step calculators out there? It's nice entering inputs and clicking 'calculate', but would be nice to know how all the inputs generate the output. Anyone know?

Hi There,

I am new to bitcoin and need advice.

I keep seeing mining 'calculators' but none of them actually shows you how the return is computed step-by-step. I want to understand how to compute this n excel so I can have it next to me everytime I want to make a trade. The part that puzzles most is the difficulty and how that feeds into the calc.

Does anyone have a step-by-step calc, or can you point me to one? I want to enter it into excel.

Secondly. I want to get more hands-on in terms of mining, and trading. I looked at CEX.io and it says that I can get 1GHS for 0.04BTC. Assuming $800 price, that is $32 for one gigahash.
That seems rather high. BFL will be offering hashing power much cheaper quite soon I hear, as will hashfast. Also, I read today that cloud hashing will be offering mining in February for $9.49/ghs.

Seems legit, as these guys were on the new york times front page couple weeks back.

Won't this, combined with BFL soon-to-come machines (and I am sure several others) cause CEX.io prices to plummet? I ask because I have just opened a cex.io account, and I want to make a bit of change day-trading hashing power.
