FPGAs exist for scrypt

Really? Can you prove that?

Whoops, I think i misread a few articles.
There appears to be some written software for FPGAs to run scrypt, but they don't work very well, and are completely DIY.
No one i can find seems to be selling preprogrammed FPGAs for scypt.

Nevermind, my mistake.

So, does this company actually have ASICs? What hardware is currently hashing away to produce the 1200MH/s I see on the website right now?

They host their own mining pool, those are just users mining in the pool.

It seems GPUs and FPGAs are no longer cost effective to mine with (as far as purchasing new hardware goes). The only opening in the ASIC market in the near future will be the from TeraHash, using the open source Klondike hardware. Should be available within two months, if not significantly sooner.

There's a number of companies attempting to do what hashrack is doing, but all are in the same boat. We'll see what happens when TeraHash starts selling.

It's very easy to see with basic math that BlockErupter boards will never, ever, pay for themselves.

http://www.bitcoinx.com/profit/
Estimates it will take 142 days to ROI.
This is increased from 119 days for last month.
During the last month the difficulty increased roughly 25%, causing a 25% drop in the value of mined work.
142/30=4.7 months
As the difficulty rises by ~20% every month for 4 months, you're going to be left with thousands in debt.

On the other hand, ASIC miners from BFL or Klondike will remain profitable until roughly Sept.
@$300 for 5gh/s and $200 for 4.5gh/s respectfully.

At their current price, products from ASICMiner are a scam.

@ $35 and 280mh/s this device would return the investment in 26 days.

That's a pretty good deal. I'll buy a few the day you release them, as long as they take <1.5 months to return.

I couldn't get my head around those people buying the 10gh/s block eruptor boards for 50btc (roughly $5,500). Those would take over 119 days to pay for themselves, and the hash rate on the network has been increasing, devaluing the reward for mined work by 15%+ in the last month. That's a lot of incurred debt for a long time.

These USB sticks are just plain cool though.

I suppose you could mine for a month, then immediately resell the device at full price. Net profit of $30-$60.

Not really a wise investment though, lol.

That's an interesting idea. I wonder how the value of the other online currency's is doing with introduction of cheap asics on bitcoin.

why couldn't they just donate them to charity

I'm getting the slightest tingling sensation from being on earth.. that greed and emotion drive the market and might make the world go round.

$200 for 350Mh/s, seems legit. Just do some quick math -ok, makes almost 2 dollars a day. Sounds gr-Wait..

I noticed the value of mined work seemed to decline by ~10% over the last month. At least, according to the http://www.bitcoinx.com/profit/ tool.

Bummer.
