Which hardware have i to buy to start mining?

[simpic]

Hello, sorry for my newbie question but i would like to start mining for Bitcoin.

I make a lot of searches on forum and i figure out this:

- mining with CPU is a loss of time
- mining with GPU is a waste of money (because video card are expensive and they consume to much power)
- mining with Butterflay products is not possible because the site is probably a SCAM and even it isn't it is stupid make a purchase and wait months for receive it!
- mining with Avalan products is not possible (no products available on its site)

So... what could i buy to seriously start to mining?

Thank you in advance for your reply and sorry for my english.

You buy nothing.

Meanwhile a few elite groups will take over mining.

Very long time before average joe can buy an ASIC miner, and when that time comes difficulty will be so high it will probably not be worth it.

Are ASIC bad for Bitcoin?

I would like to buy a bitcoin miner right now.
Is it possible?

[redcomet]

When bitcoins were worth $1 regular joes could mine them without investing thousands.
When bitcoins are worth $100 then it becomes more of an investment to mine.

Makes perfect sense to me - and imo more than enough people have enough money to keep the network decentralized. 

More than likely you already have the equipment to be able to mine coins, if you have a desktop computer with a video card then check out the alt-coin section to mine some cheap coins that don't have very high difficulty.  Or, you could also buy from a hosted mining service to get started asap.

I don't have a desktop computer, just a laptop.
I'm searching the web for some USB FPGA cards, like Cairnsmore, Ztex, Terasic and so on that i would like to use with my BitMinter account.
None of these cards could be a good investment for me?
Theirs cost is under USD 1,000.

It won't be a very long time.  It's just new technology now and those who got on board early and risked with the right producers will profit most, as they should.

As the technology is easier to produce, more will do so and that supply will drive down the price of the technology in line with profitability similar to what GPUs have seen over the past few years.

The specificity of the hardware is a legitimate concern, as is how difficult it is to currently get an ASIC, but both will work themselves out through market forces.

Through all of it, and even right now, current miners have a vested interest in saying:

difficulty will be so high it will probably not be worth it."

No they would be a VERY BAD investment for you.

go here:
http://tpbitcalc.appspot.com

Type in the details, BUT remember that the difficulty is generally changing about 9-13% UP each month....

It would take AT LEAST a year to regain your investment(if you ever do).
Far better you take that $1,000 buy bitcoins and sell with a 10% change, that way you make 10% in a week or so........
Wait for it to fall 10% re-buy.... then sell with a 10% gain..... (5-8% is currently the swing on bitcoins in a DAY...)

If you are good then you could make 100% of your money in a few months, just because the cash is burning a hole in your pocket no need to do something stupid......

simpic, (valued at the performance) I would not suggest to invest USD 1,000 in FPGA or comparable devices at this point. Although I did too, I can not recommend this anymore. Please take a look at the calculator in my signature, you'll easily find out that just buying BTC would be the best kind of invest compared with ANY mining device you could have on hand the next days.

there are only very few pro's, e.g. you can sell the FPGA in case of bitcoins will become worthless.

[simpic]

Thank you for your reply!
...what about do the same (buying any FPGA) for mining alternative coins?
Could this be more convenient?

no fpga can mine script

What about buying Butterfly miner (800 MHash/s) on eBay?
Their prices are about 1000-1500 USD but in this case i will get it in few days!

I used this calculator http://btcinvest.net/bitcoin-mining-profit-calculator.php and it should be profitable.

What do you think?

800mh/s will NOT be profitable when the difficulty doubles very soon.

[Preschoolv2]

Buy a bfl preorder and jump the huge line.

[ganabb]

a HD7870 has a maximum TDP of 210W, so while your GPGPU bit-coining probably wont hit more than 85% loading.

I am also watching out for ASIC availability, but nothing is really there yet.  I would suggest you either save more cash and wait for a good company to start putting out ASICs (which others have said could be a long wait and/or questionably profitable with difficulty rising)  or just go with a GPU.  Yes a GPU will cost more in electricity to run, but it is still profitable, it is available, it can do scrypt coins, and it will have resale value if/when you can't mine with it anymore.

Have you tried that link? Even the difficulty grows it is still profitable...
Please have a look and let me know what you think about my idea.

Thank you.

simpic, please dont forget to try the diff increase at 40%. the diff will jump round about 25% the next days, it will be more than 40% up in total within less 4 weeks timespan.

EDIT: and as no one can know for sure the future btc/usd value, you should consider all mining investments as BTC to BTC investments.

The different level is 15.6 million now, a jump of 28% from the previous one.

And the next jump will be about +33%
