Bitcoin Forum

Hi guys,
sorry for me english, i just a novice in this language. A month ago i have:

1x7870OC (Pitcairn) 440Mhs~ OC 1220 68ºC
2x7870xt (Tahiti) 510Mhs~ OC 1200 71ºC
1x7970 Vapor-x 680Mhs~ OC I don't remember...
------------------------
2.1Ghs mining in total (1500€-1900$). In the actual price and difficulty of Bitcoin in 6 month recover the inversion, but the difficulty are quickly increasing.

I made ​​a bad decision buying? It's time to sell the GPUs and buy a ASICminer/Avalon/Butterfly?


Thanks a lot for your time!


The cost of electricity it's not important.

Mine Litecoins instead, they're still profitable for GPU mining (and if electric is free, CPU mining too).

According to the calculator here (http://www.bitcoinx.com/profit/) you are making about $342 USD a month if electricity isn't a factor. Why would you turn that off and sell the parts?

just keep mining,  sell when price goes up.

Tough call. Everyone's situation is just a little bit different.

Personally I'm out in late June. Partly though because my few mining rigs seem to be taking like 5 hours of maintenance a week as of late.

GPU mining is in terminal decline though. It's pretty much over. We are on third gen mining now; it's the ASIC era.

However I'm not saying there will not be profit to be made in GPUs still...especially if you'll be working on the ALT coins, such as the very promising upcoming Netcoin, for which no ASICs will be working on.

ASIC for Litecoin ? hmm maybe next year

Seriously ?

I restarting GPU mining only 3 months ago.

I switched over to litecoins 1.5 months ago.

I added a secondary GPU mining rig 2 weeks ago.

Not that profitable, but for making 250$ a month on litecoins, I have no reason to back down.


Specially if you said electricity is not a factor.



Like a dumbass, I sold my original GPU miner in 2011 when it crashed to 3$, when I was making 2 bitcoins a week with 2x5850's.

What a mistake that was, so I am never stopping again as long as I get even 1 bitcoin a month one way or another.

My biggest mistake - SOLD two rigs @ 4GH/s when BTC price per block was 25BTC (first days) everybody was in panic that GPU mining will be no longer profitable. 
Same happening now

I sold a few cards over the last year and regret every single sale.  I was always thinking that "next month has got to be the last profitable month for GPU mining" and then the difficulty hike never came to the extreme everyone said it was.  It will happen, but in the mean time, profit is profit.

Newbies will need some kind of cheapish alternative to keep in this.  Hopefully smaller USB Asics become affordable and highly available.  Its easier cashwise to manage than dropping $5500 on a blade.

Dropping $5500 on a blade works out to about the same $$/MH as a good GPU. 

Jalapeno and other BFL vapor-ware is priced better as far as $$/MH, but real MH are available at Newegg and Fry's, while the BFL MH is virtual.

True but its easier to manage it $300-500 at a time.

lolno

it's marginally more profitable than bitcoins right now. but if every gpu miner switches to litecoin, you can be sure that difficulty will skyrocket.

That was my point.  Dropping $5500 does not buy you much.  Lower J/MH, or electricity savings, yes.  Not much else.  Once better or lower cost ASIC miners come along, your $5500 card is still the same $1.87/MH as the GPU's and has no value other than mining.  GPU's can be sold to gamers as long as you haven't damaged them.
