Title: Block Eruptors and Why?
Post by: nahtnam on August 02, 2013, 12:55:52 PM
I dont understand why people buy things with 355 m/hash. Why should I get one? Should I get multiple? And where can I buy some with BTC and not USD or EU...

Low power usage and probably the biggest reason..... you can actually get them! Any other ASIC device out there has a 4+ month (1 year in some cases  ::)) wait time. You can order a Block Eruptor and have it in a few days.

Its really no different then people buying a bunch of video cards a while back.  I know there are a bunch of differences between GPU's and Erupters but they really are the GPU's of modern mining.

Quite simple, really.
It's pretty much as powerfull as a high-end ATI GPU, but at a fraction of the power requirement.
An ATI HD7950 will set you back around $300 (or €260), will consume around 250-300watts of power and give you 360-380Mh/s.

An USB Block Erupter will set you back 0.5BTC (roughly €40 or $50, see forums for groupbuy), consume 2.5watts of power and give you 330Mh/s.

In short: for the price of one 7950 you can get 4 USB-BE's, so thats 4 times cheaper already. Effectively, you get 3,75 times more hashing power for the same amount of money.
Then comes the power requirement. You could virtually power these things from pedaling a bicycle an hour a day. (just put an alternator on, hook up a large battery to store power and control the BE's with a RaspberryPi or a modified router running Linux)
They really won't increase the power bill. A single 7950 will cost you anywhere between $10 and $30 per month to run 24/7 (depending on where you live), wich at the current exchange rate (BTC->USD) will never pay for itself.

ASIC Miners are cheaper.

You get more Mhps for your money.
It consumes less energy.
And probably will give your investment back.

I began with a USB Erupter.  ;)

And even with that it will take a few months to get it back. IF Bitcoin price doesn't drop, if it does longer. If it goes up to 200 ill be very happy in afew months.

People forget that you can mine alt coins

You can buy BTC through the currency exchange sub forum, plenty of options there

Yes, video cards you can mine any coins, while eruptor or ASICs you are stuck to only BTC which at very high diff.

Sorry, but not true. You can mine some more profitable alt-coins which uses SHA-256 algo also.

I'm mining PPCoins with eruptors, for example.

And in what website you can exchange PPCoins to BTC?
