Mine at Jonny's Pool

Correct me if I'm wrong but if 5 usb miners find a block on CKpool don't you have to mine the block first. Wouldn't that take another longtime do solve it.

If you've found the block, you've already mined the correct hash to add it to the blockchain. There is no more mining that needs to take place on that block. Of course, finding a solo block with 10GH/s... well, at the current difficulty, you would expect it to take nearly 673 years. That hasn't stopped me from pointing my 5 U2s at ck.'s pool, though. I've got a 1 in 245579 chance of finding a block today

2 gridseeds gathering dust
1 antminer s5's (was going to buy another but the price jumped up)
2 antminer s3's (i want a few more, pm me if you have some cheap)
3 Zeusminer Thunder x3 (these drink power like crazy)
2 Zeusminer Blizzards (these are what got me interested in mining)
5 loose hashingboards+ heat-sinks and fans ziptied over them from a damaged GAW war machine i think

i pay around 0.04 cents kwh on average for commercial power on off peak hours
I turn everything off during peak hours except today with my scrypt miners because whoa! Shocked

you have not actually found a block on the pool, everyone else have contributed to find it, it's basically usless to find a block in the pool and not only that, but finding a block when you mine in a pool is not the same in finding it in solo

5 of most usb miners will not get you anywhere very quick. A lot of pools have minimum payout so look at that if you are truly mining with 5 usb miners.

And chances of solo is very very bad. It could happen but just such a slim chance.

Antminers: 1x S3, 1x S5.
I plan to acquire three more S5's over the next three months. Working on a discounted power option to keep things profitable.

If anyone needs hosting (I see some heat complaints) we're the lowest cost option. $63/kW, located in northern Canada.

Bitcoin isn't a bubble. It's the pin!

I have a few antminer S1's but I currently do not have them on because of the summer heat. However, I may consider turning them on within the next week or two.

I am using Radeon sapphire HD7950 and is giving me 300kh/s on scrypt coins, I am using free electricity.

Pick and place? I need more coffee.

5x 700Gh monarchs
20x 16chip bitfury boards (undervolted) and 30 spares
4x Avalon3 blades (undervolted) and 2 spares
2x Antminer S1 (undervolted) and 10 spares
2x Technobit hex4m minion boards
1x Habanaro
3x Asicminer BE200 tubes (undervolted)

Tons of BFL 65nm stuff collecting dust.
Tons of first gen Asicminer stuff collecting dust.
Some Rockminers 32Gh and 100Gh gathering dust as well.

Power is pretty cheap here and have a solar kit on the way. As long as I keep it around 1w/gh or lower I am good. Grin

Remember when my two HD5830's+Geforce 260 made more BTC than all of this combined. Cheesy

Only kept 1 Gridseed 5 chip I bought locally in my early script mining days, just for the lulz Grin

Mining at 0,22 $/kW/h, obviously not profitable, but I like the little thing

It's a bit like a token, a reminder, it was the first one I had.

I have 10 Antminer S1 and some Metabank Bitfury miners.
All of them is downvolted, so it uses about 1W per 1 GH/s.
Electricity cost is $0.05 per kWh.

I had 3 S3's that I sold and bought an S5 with. I'm looking at getting another S5 and then probably an S4+ two would be amazing Tongue

.

Check out my thread for ROI here guys if you ever question what S5's will do in your area.

Have 2 BFL Jalapeno's (16gh total), 2 S3+'s (averaging a bit above 1th) that I still run. Could run my S2 but its too hot for me to do so until winter comes around again. I probably should get rid of my S2 and my SP10 (or the bad ebay buy). May get some U2's just for fun as well.

I laughed pretty hard on that one Grin

Rather than fire up an old HP server, you can easily plug those sticks into an rPi, or even whatever laptop you're currently using. I've got 5 of them in a powered USB hub, and that hub is plugged into my rPi. The rPi has cgminer 4.9.1 compiled from source running. I point them to -ck's solo pool because you never know

.

The cost to run it is virtually negligible... the U2s draw about 12.5W total and the rPi about 2.5W. 15W total consumption costs me about $0.04 a day. With your insanely high electricity costs, that same setup would cost you about €0.10 a day. Since you're only talking about 2 U2s, that would be a total power draw of 7.5W and about €0.05 a day. Pretty sure you could slip that one by the wife without notice Tongue

.

Of course, solo mining with only 2 U2s, you've got about a 1 in 617589 chance a day of finding a block at current difficulty levels... but at the cost of playing, it's worth it.

It's actually a very good idear... I am, however, one of the few reasonably tech savvy guys on the planet that doesn't own a raspberry... I do have an old neoware CA22 laying around. I might try to install a linux distro on it, and run it as a server. It also has 2 usb-ports, so i might just plug the U2's dirctly into the thin client (don't know if this would be possible, with the heat and the fact they do draw a couple of Watts).

They're well worth the minimal investment. The new ones will run some version of Windows 10 (if you're into that sort of thing). At $35 (not sure what they're priced like in your area) they're a steal. Of course, getting that old neoware up and running might be a fun project, too. Not too much power draw, and those USB 2.0 ports should be able to provide enough juice to drive the U2.

Mine at Jonny's Pool

I think one thing worth mentioning here is that all of the numbers provided thus far are based upon current conditions: the current difficulty, the current exchange value of BTC, etc. As things stand now, with BTC valued about $250, you've got to have extremely cheap power costs to break even, much less make a profit from mining. The hardware you're using obviously has an impact as well. Using a GPU to mine BTC is absurd because of the high power to hash ratio. Even the currently available, most efficient ASIC gear is still between 0.4 and 0.5W per GH/s.

Things change quite a bit if the exchange rate of BTC goes to $1000 a coin, or some new hardware comes out at 0.1W per GH/s, or the difficulty drops dramatically.

no miners anymore (I had FPGA Acarus, Avalons and few KNC Jupiters back in good old times), reg. electricity ~0.2$/kW, so even new generation will not work for me:(
