Profit probability from 50+ USB miners

[steve321]

I've acquired a few USB miners, and am inclined to buy more.  Would I break even at the current rate / difficulty?

may i know where you get the usb miner?

It mostly depends on the price you pay and what happens to the difficulty. If the current trend continues, a USB miner will earn less than 0.4 BTC. So, you shouldn't pay more than that for a new USB miner. Power costs are currently very low for ASICs, so there is no reason not to mine with the ones you already have.

Check out the Genesis Block Mining Dashboard (http://mining.thegenesisblock.com/). You can test different scenarios and decide what to do.

Acquired a few?  That leaves too many unanswered questions - cost, total ghz, time available to mine with them, environmental conditions, do you pay for power, what's the cost of the sticks...  Use one of the many calculators to find out ROI - mining.thegenesisblock.com is OK...

Bottom line is most likely the USB sticks will not pay for themselves at the expected difficulty...

If the calculator is accurate, it appears pretty sad. Seems that the difficulty goes up rather quickly. Does it really increase 75% per month?

welcome to the wild world of speculation....  Nobody truly knows how quickly difficulty will increase but there are 400ghz units claiming to be ready in 8 weeks so there will likely be a huge jump in difficulty in October and then it'll level off for some time.  The 75% is high in my opinion but its not out of this world.  I usually use 50% to make myself feel better!

It has been going up an average of about 50% per month since February, when ASICs started coming online. In February, it was about 3 million and now it is about 40 million.

Next difficulty is estimated at 45M or so right now.  I've seen what some of the hardware usually sells for, and it would be difficult to make a profit.

today mining difficulty is estimated  at 37m .... for example if you start mining with 50 usb miners (16700 mhs) you get around 0.25 btc
