Block Erupter question

[piplupgao]

How much money per day (dollars preferably) will I get with 4 Block Erupters on a raspberry pi

[Vitalius]

How much money per day (dollars preferably) will I get with 4 Block Erupters on a raspberry pi

About $0.10 at most and $0.01 at least.

really I expected a lot more

What is your buy in price? How much per USB ASIC?

You will likely not make anything with these ASICS. They will cost you more than you will ever make back. The only benefit is a slight increase in overall network hash rate increasing the overall security.

 

You can use this site to check profit margins and calculate various things.

Those ASICS provide 330 Mhash each and will only work for SHA-256 algorithm. Currently you will see 34 cents per day for each miner on the current 50 million difficulty. The constant increasing difficulty will prevent you from ever making back the hardware investment based on how much you pay for these.

no, that is far to low I get around .015 BTC after the recent difficult change  ($1.50 a day) PPLNS mining

So are there any more efficient ways to mine?

[RuecanOnRails]

If you want to take a look at some of the ASICS and how they compare to each other check this site.

https://en.bitcoin.it/wiki/Mining_hardware_comparison#ASIC

 

Compare the Mhash/$ value. The Block Erupter is one of the lowest value ASIC and is long outdated.

 

When it comes to mining for profits, you need to go big. Something along these lines.

A 400 Ghash miner which costs $8000 and a proposed October delivery date. One of those might be profitable for a little bit in terms of paying back the hardware costs and seeing profit.

Instead of looking into mining Bitcoin and SHA-256 based coins.

 

Look into GPU mining Scrypt based coins http://coinchoose.com/index.php

They offer a much larger profitability over bitcoin when mining hash is compared.

 

The difficulty for scrypt based coins is much more stable, while it does raise steadily, it's a much slower rate for the time being. A GPU farm will last much longer in terms of profitability compared to ASICS on bitcoin.

so what would the most profitable setup under $1000 is

[RuecanOnRails]

so what would the most profitable setup under $1000 is

 

Not going into details of exact building or costs.

 

A rig with 5 7950's. You can find them for about $180 each. Of course you may spend more than $1000 on the full mining rig depending what parts you can salvage from other places.

 

Each 7950 can get 650 Khash (Khash on scrypt is  +/- M/hash on SHA-256)

With 5 7950's you will see 3250 Mhash.

 

Just looking at Litecoin, as it's the biggest alt coin available.

https://www.litecoinpool.org/calc?hashrate=3250&difficulty=913.23607235

 

If you jump blockchains based on what coin is most profitable based on http://coinchoose.com/index.php

You could potentially double the amount claimed by the above calculator.

how do you get 7950s in one rig

How long do you think this will continue to be profitable

how do you get 7950s in one rig

 

Mining does not require the full 16x PCIE bandwidth. You also want to use converters/extenders. Something like these http://www.ebay.com/itm/5-pcs-PCI-E-Extension-Cable-1x-To-16x-Slot-Extender-Riser-Card-Adapter-Pic-New-/281150853900?pt=LH_DefaultDomain_0&hash=item4175e5930c

No one can say, but when the profitability starts to drop, you can sell off parts of the computer.

 

It might take 6 months for your hardware to break even. By which point a lot can change. If you're worried about your investment, you could always buy the coins directly. Never spend money you don't feel comfortable with just throwing away.

 

I got into mining for the learning experience more than profits, I like the idea that I can help take part in building the future of money.

I want to make a real profit other wise I would just mine off my gaming rig

that should look interesting

[RuecanOnRails]

Here's a link of a mining rig built in a milkcrate (best option, due to open air and easy cooling)

https://bitcointalk.org/index.php?topic=66432.0

 

That one is using 2 rigs in one small space, you can get 5 GPU's on one rig.

If you scroll down in that thread you will find another user posting an image of his crate miner running 4 cards.

 

 

Here's a more elegant design.

[Whaler_99]

Using extenders is how I Fold with 5 GPU's in one system - works fine.

 

The only thing to remember, 5 x 7950's means you going to need a solid PSU, with a single 12v rail, as you going to also be tapping into some Molex power connections.
