Has someone the cheaper group buy for Europe thread link? (It's all about monne...BTC)

Is there already a cheaper USB miner group buy? Didn't know that. We are trying to get things going in the Dutch section, but nothing really happened already. So we are also looking for options! Smiley

Searching for a trusted escrow service? Check my trust. I use a Trezor device for my escrow services, so your coins are safe. Fee: 0.5% or 0.05 BTC, whichever is lower

Hi,

I made some small progress... I am currently mining on a MacBook Pro running OS X 10.7.5.
But... only using Win XP running in a Parallels 7 environment.
There I installed the 3.0.2 bfgminer (32 bit version) and the CP210x drivers:
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

Next step for tomorrow: Copy the VM to the Mac Mini and try it with all 4 USB ASICs and the Ztex
Boards (running natively on OS X).

I have 77 of the little things........ 19 laying dormant at the moment   Cry Shocked Cry

Can they be set up on a Mac easy? I am completely illiterate when it comes to Apple products and their operating system, but my Mrs owns one of them, maybe i can link the other 8 upto this? I have the hubs Smiley


Sweet baby Jesus. 19 dormant... I would love to take a few off your hands to help out Smiley


You are a God for putting this all together successfully.

macs are for people who like using computers but dislike having to tinker with computer hardware.

similarly, usb erupters are for people who like bitcoin but don't have a spare room in their home for big aluminum frames full of GPUs and huge noisy fans and PSUs.

not surprisingly, some mac owners have ordered usb erupters.  Wink

No longer buying/selling Casascius coins (okay, except for this one: 1Ag1g59y). Beware scammers.

I'm a Mac boy.  I bought a new/used Asus laptop as a designated miner.  Macs are hard to configure for mining and the major majority of the community uses pc's.  I have my Asus, USB hub, and USB fan ready to go.  Waiting for eruptors.  Also waiting for BFL, but who isn't?

The last couple of series of Macs have either had nVidia or Intel GPUs, both are useless for mining, so something like the erupters are a reasonable option. Same goes for PC and laptop users that don't have ATI video cards, Mac owners are in exactly the same boat.

I have my Erupter working Mac OS X -> VMWare Fusion -> XUbuntu

cgminer 3.1.1 with -S

I can't get cgminer 3.2 to work.  /dev/ttyUSB0 gets disconnected as soon as cgminer 3.2 starts up and cgminer doesn't see anything to mine with.

I jumped through a bunch of hoops trying to get 3.2 working but in the end, with 3.1.1, the only thing I needed was -

adding myself to the dialout group.

( Had three ports that would not accept any Erupter USB that was plugged into it, but worked fine in any other slot. *shrugs* )

OMG .Fools and their money!  When this was announced difficultly was under 10m and network hashrate under 80t/h.  Now you've got them it's 12m (+20%) and network hashrate is 100t/h+ . In under 3 days difficulty will hit 14.4m.  So thats a 44% increase in diffuclty in 5 weeks, around the 30% + a month I predicted.

5 weeks ago each of these would have made you $1.84 a day for the first week. Now you are only making $1.51 a day and this will drop to $1.27 a day in under 3 days when difficulty hits 14.4m.

So lets forecast from there shall we! Starting @ 0.0104 BTC and $1.27 profit a day for the first 10 days. 1 month profit $38.  3 month profit $90. 1 year profit $155!

May I remind you that BTC has gone up only $10 in the last month. And you have paid $220 for each of these last month plus the 1/9th cost of the powered USB hubs and fans plus the cost of all the shipping and customs charges of the USB miners and hubs and fans.

And looking further ahead after 2 whole years of mining with $0.01 per day powercosts for each USB you will have only made $158. Yep, @ 30% increase a month you will make a whole $3 in the second year. Buy the end of year three these will not earn enough BTC to cover their power use!

You lot will have to pray (and hard) that BTC difficulty slows it's current 30% a month increase or that $/BTC steadily rises to over $250 in the next few years or you will never make a ROI.

To big a gamble to stake way over $12k on. Good luck though, I admire your balls, and I thought I was risky putting $900 into 3 x BFL 5 g/h miners (15G/H) to arrive this side of Xmas.

 I've calculated I will make back the BTC  spent on this outlay within the next 120 days, even accounting for difficulty increases (And to be clear, am reinvesting previously mined BTC accrued over the last couple years)

 Am OK with that.

I've tried to run the numbers but the very best case scenario I've calculated for your setup is break even in aprox. 200 days, and that with a ridiculously optimistic 0.5 yearly profitability decline (which means that in the next 12 months difficulty would only double, and we know that won't happen).

Could you share your numbers, Xian? I'm very curious about them.

Admittedly, I suck at math, so it's quite possible I'm off my a couple weeks with my ROI estimates.

The 120 day figure is based on my current extrapolations, considering that my existing, paid-for operation, already brings in x BTC per pay, I'm going to be getting x + ~1 BTC more per day for the next little while just with these additional ASICs.

I hope you can appreciate me being intentionally vague.

Don't worry guys, when the global currently crisis occurs, bitcoin will skyrocket, as will gold/silver.

Maybe you are not THAT off in your ROI estimates if the ebay post announcing this setup (using your picture) keeps going higher ( and IF it's your post anyways Smiley )

I don't keep up with eBay listings. A user approached me about using my images. Said sure why not.
