Will people ever get their investment back on USB Erupter ?

[sacramento]

Each USB erupted cost about 2-2.3 bitcoins, and has 333Mh/s hash. According to calculator, it generates 0.25 BTC per month, at the current difficulty. This requires at least 8 months to beat even, with rapid diff increasing, I think people who buy USB Erupter now will never get their investment back. Any comments?

[R3dcell]

Unless they bought in bulk, or are in it for the very long term, people will most likely not make an ROI. Also, the price has already dropped on the Erupters and its going to keep dropping I suspect. This is why you see a lot of people selling off Erupters and blades, they overspent on the hardware, and now its losing value before they could make a ROI.

Even in bulk it is 1.99 BTC I think. Same conclusion. I don't see how the investment can be returned, with so many ASIC is pouring into the market.

[R3dcell]

very true. Id like to get a few myself but am opting to wait a few weeks and see where the prices are at.

I am doing the same too, the flip side is that the diff is going up quickly, because many ASICs released into the mining

[saveawedge]

If you were one of the first to receive, a ROI was just about possible. I'm also watching to see what price ASICminer set the new batches at.

[R3dcell]

yeah


Probably wont even be worth having an Erupter once the difficulty goes up a bit more. I wish I had the money to invest in a BFL Jalapeno or maybe a KNC miner when they come out.

[macintosh]

I doubt they ever will.

[crashzilla]

3 to 4 months

3 to 4 months

no way. this just isn't possible at their current price and hashing rate of ~330MH/s

I believe between 1-2 years, after that you will make bitcoins. not bad as a hobby with 1 Unit but impractical to run serious hash with many of these units for profit

O_o

what you "believe" is completely irrelevant.

Either you can do maths or you can't, and you can't, apparently.

Well, if you believe the hashrate will stop increasing then it's relevant.
However I think it's very unlikely that this will happen. Even if the same amount of people will mine in the future, technology will advance.

Anyone who buys USB erupters now will lose out bigtime

Correct sir!

[rumpler]

Yeah, as others have said, blockeruptors are pretty unprofitable at this point.

I'm surprised by that one video going around with the kids and the bitcoin mining farm, where they had something like 50 units of the USB model. Someone argued that if the Bitcoins they spent on them were mined long ago, then the "cost" wouldn't be that high for all the units, but the opportunity cost would still be huge...

[escrow.ms]

blockerupters might be good for other stuff, but not good for mining bitcoins at current difficulty.

[Alexander The Great]

Isnt bitcoin increasing in difficulty sometime next year? I imagine thats when the new erupters will come out

[btceic]

Let's do some math:

~1 GH/s ~= 0.025 BTC per day

1/3rd of 0.025 ~= 0.0075 BTC per day per USB
0.025 * 0.30 == 0.0075

Original cost of 1 USB = 1.99 BTC, let use that figure just to be fair, as this is the lowest price you could/can get it for right now.

At the current diff, it will take each USB 266 days to reach your original investment, not including any electricity that you may have used.

diff is currently jumping 15%-28% each 10 days or so.

Depending on what your cost basis is of your bitcoin, I would say the answer to this question is a resounding no.

I seriously don't get why people are paying 2BTC + for these things.
