Those are standard currency's and a dollar in your bank account is only gonna pollute as much as it takes to keep that stored and managed.
Point being the mining is just polluting without reason unless you can produce it green using energy for something that could've been brought to market without it is just bad.
You don't see Paypal doing this you don't have to mine to make transactions in that Paypal system.
As I'm from a country that technically invented banking I would say we should go back to the banking system where the bank has 1 dollar for every dollar they invest or lend instead of what those republicans authorized in the 80/90's yeah you can lend/invest 100 dollar for every 1 dollar you own. (that would be fine if lending actually returned as it should and investing gives you a profit or is on a extremely low scale)

I'm no one to say how you should spend processing time and power but I find folding and other tasks that actually help more high profile.

The value of bitcoin, or any crypto, has little to do with the work put into creating the coins. Just like any other kind of money, it's backed by how willing people are to use it as a medium of exchange.

Mining doesn't provide backing, it's just a control on supply.

Honestly, I would not be remotely surprised if the net benefit of crypto currencies eventually exceeds that of any other distributed computing project, including F@H.

Reliance on banking systems and government fiat currencies are an evil at least as destructive as cancer. Those who participate in the creation and use of cryptos are taking what may be the first steps to a really viable alternative.

That might be true actually weird to say but maybe I will connect a few dedicated rigs to my new folding rig via usb I could justify my purchase by partially paying for it.
My parents don't care how much electricity I consume as long as it isn't totally wasted (we have a lot of solar panels in the day power comes almost free and what we have too much we sell back)
I will discuss this I've changed my vision on this a bit if BC makes it into a full currency with a stable exchange rate like current currencies I will support it for sure.

Hmm...I'm more looking for efficient way to mine, not debates smile.gif


The jump to 15 million difficulty is interesting.. Not sure what do do now for mining...It won't be long until its over 100 million. I want to continue generating cryptocurrency but I nee to do so efficiently. I actually am looking into creating my own little solar farm. Unfortunately I don't live in a particularly great place for that...I would need many panels I think.

Bitcoin mining is rapidly becoming the sole province of ASICs. GPUs just won't be viable much longer, not when hardware that is 10-100 times as efficient is out there. I've already moved most of my GPUs to Litecoin (the only alt coin I've got anything resembling confidence in).

Anyway, improving efficiency when GPU mining pretty much comes down to choosing the right parts, stripping out what you don't need, and using optimal clock speeds/voltages.

The only purpose built mining system I've got consists of a cheap MATX H67 board, a PSU, an old laptop HDD, a single core Pentium G440, one stick of ram, and a pair of 7950s; no case, no extra fans/drives, nothing. Anything more wouldn't contribute to mining performance. As it stands, 90%+ of the power consumption is the GPUs and if power was the concern, I could probably almost double hashrate per watt by underclocking and undervolting the cards, instead of overclocking them.

As for alternate sources of power wind/water is more viable than solar in many places.

Very true but you have the option to use the Solar power to generate hydrogen which ensure you can store the energy and use it when you need it which is a great plus.
Of course you could also use the power generated by wind or water to do this water being the most viable as wind isn't very constant (Where I live it is though mad.gif )

Bitcoin is well past reasonable profitability IMO since it now takes more than 5 months to break even on a $300 HD7950 after counting electricity:

LTC (or other scrypt based crytocurrency that's actually legit) is probably the best we have at the moment since it's ASIC hostile

I have made the switch to Scrypt last night, still looking to increase efficiency though smile.gif. Unfortunately the 77XX GPUs don't seem to mine scrypt well, not sure why. Anyone mining scrypt on the 7750/70/90?

perfect thread for me, i was just doing some researching and i wanted to join bitcoin but i got a few questions

1) how offen do they pay out?

2) what is the best card to hash?

3) can i hash more with sli or crossx

They don't unless you join a pool.

CF as AMD cards are better than Nvidia cards for hashing but you don't need to have them in a CF setup it actually works much like F@H node based hashing.
