Bitcoin Forum

Hi.

Looking on this  (https://en.bitcoin.it/wiki/Mining_hardware_comparison) website there is a miner that can mine 7,500,000 Mhash/s its called Xtreme Miners The "Lion". Now I know that people are saying that mining isn't profitable but I cant stop looking at these figures.
is it really as good as it looks?

looking at mining figures I have input I get this:

Coins per 24h at these conditions 5.3319 BTC
Power cost per 24h 8.10 USD
Revenue per day 4254.78 USD
Less power costs 4246.68 USD
System efficiency 3333.33 MH/s/W
Mining Factor 100 at the end of the time frame 0.03 USD/24h@100MHash/s
Average Mining Factor 100 0.04 USD/24h@100MHash/s
Power cost per time frame 2958.53 USD
Revenue per time frame 1226152.46 USD
Less power costs 1223193.93 USD

8 dollars a day seems like a lot of money for the machine... thats a lot of power

i don't trust that company.

much better to buy from KnC or blackarrow, they have already proven to be reliable.

Insanity , good luck pal, that might be another butterflylab

8 dollars per day? A beggar would earn more moneys...

Before buying, you should ask yourself
1) Is it on preorder?
2) How much is the risk?
3) Will I be able to hit ROI? ( Include electrical cost)
4) Any trusted feedbacks about that company, if its reliable.

too bad they are labeled as scam all over the forum.

Thanks for all your replys, $8 a day is the electrical cost not the bitcoins generated, the bit coins generated are 5 a day.

Less power costs 1223193.93 USD

There is already a thread regarding xtrememiners: https://bitcointalk.org/index.php?topic=345612.0 (https://bitcointalk.org/index.php?topic=345612.0)
As a german guy seems to be responsible for it, interested users can call him.

If they have machines that can do this, why would they sell them instead of letting those puppies mine for themselfs?

guaranteed cash
not dependant upon exchange rates.
cash flow? just guessing.

That can be said for every single mining rig ever sold.  It's 'because they rather not speculate on bicoin value/price, and make 100% sure profit in USD from a machine they can sell for very good profit.  That's like saying "why do companies sell fishing boats, when they can use their own fishing bots to fish, and sell the fish". 

why sell the fish when you can eat them lol!!

So I assume that no one out there has a machine that can hash in the TH/s category? If these figures are real then can anyone think of a reason why not to do this other than the price of the bitcoin dropping??

I believe I read somewhere in this forum that Extrememiners are scammy. Personally would trust BlackArrow (again as I read from here, but no experience yet).

So based upon the figures from a mining calculator.

if I bought this http://www.blackarrowsoftware.com/store/prospero-x-3.html?sl=en
and had 2000mhs then my farming rate would be Coins per 24h at these conditions 1.4218.


Can anyone confirm that this is correct? also would you get the speeds constantly?

I would not give them any money until they prove those machines exist.

It might be true if you have one today. But if you have wait long and many other preorder it as well, it is question if you might make profit

It is a gamble for sure, but if you wait until there is proof that they exist, it is already too late. There will be too many orders in front of you and by the time you get your miner, it will not be profitable any more. Butterfly Labs orders ran into the same problem. I ordered my Jalapeno late and it took 6 months to get it. Now I'm only getting ~0.004 BTC per day with it, having spent ~$170 on the miner. It will take a while to pay for itself at that rate.

I can't trust any of that data considering those morons claim the price of a Neptune is $7K.

yep it will mate at that rate.

what do you mean?
