USB miner

[BitcoinSupremo]

Pretty simple and maybe dumb question but what you can mine per day with a 20-50 USB miner from Ebay?

HexFury is one of the USB ASICs with the highest GH density. It has a 11GH/s and is quite expensive. You are expected to earn around 0.01BTC per month before factoring electrical cost and difficulty increment. Did I mention it is $70 per? You are required to get a good USB hub to power all of them. Buying Bitmain S3 and better would give you a better chance at ROI.

Its 0.00033 BTC per day, I can live with that as my electricity will be payed by others, don't care about 70 USD either. I just need it to just plug it in my pc and start mining, I don't want USB hubs or anything to power it up. If its plug and play I may go for it, if it requires adjustments then I am not going for it, but thanks for telling me which is the best USB miner.

i think buying an ASIC with the same hashing power will be cheaper and ROI faster.

Overall cost might be a constraint for some...

Is this the only good option available if you talk about usb miners.

Here are the expected generations for 11gh/s 20gh/s and 50gh/s.  Whoever said .01 for 11gh a month was off by about 81 years.  Also remember the reward halving will occur in a couple of months so all the payouts will be cut in half then.

Code:

The expected generation output, at 11 ghps, given difficulty of 165,496,835,118.226348876953, 
is 0.00003342645 BTC per day and 0.000001392769 BTC per hour.  Given this rate it will take you 
81 years, 50 weeks, 1 day, 10 hours, 17 minutes, and 0 seconds to make 1.0 BTC

The expected generation output, at 20 ghps, given difficulty of 165,496,835,118.226348876953, 
is 0.000060775364 BTC per day and 0.000002532307 BTC per hour.  Given this rate it will take you
45 years, 4 weeks, 1 day, 0 hours, 51 minutes, and 21 seconds to make 1.0 BTC

The expected generation output, at 50 ghps, given difficulty of 165,496,835,118.226348876953, 
is 0.000151938409 BTC per day and 0.000006330767 BTC per hour.  Given this rate it will take you 
18 years, 1 week, 4 days, 14 hours, 44 minutes, and 32 seconds to make 1.0 BTC

The Compac by GekkoScience (aka sidehack) is pretty good although at this point you can only get them from re-sellers.

It will do ~8-10 gh/s on regular USB power but can be overclocked to near 20 gh/s if you have a USB hub that can supply enough power

18 years to make 1 BTC, well I guess I am not buying anything from those, I don't know if I will be alive in 18 years
