What's the plan for the GPU rigs post-shutdown? Sell them and use the coin to pay a dividend or sell them and use the coin to buy ASICs?
Sell to buy the next round of ASICs. However the 7970s (undervolted and underclocked) will be profitable longer then the others, so they will get sold last. Also it may be possible to turn a profit with the 7970s mining Litecoins once they are unprofitable mining BTC. I haven't looked into what card is most efficient for LTC mining, but I'd hazard a guess that it is a undervolted/clocked 7970.
Actually from when I tried to mine LTC on my 7970 rigs the 5xxx cards are better at that
Bleh, I wonder if its a software issue, you'd think 7970s having more cores would mine LTC faster
I dug around a little, it looks like some peeps are getting 7970s to perform for LTC. I also took a look at the LTC market, its pretty small, if even 10% of BTC hardware gets repointed at LTC, it will make it unprofitable.
This is assuming the price doesn't rise at all. Obviously that will not be the case if 10% of BTC hardware (i.e. GPUs) get pointed to LTC and it is unprofitable already.
People mining LTC back in April in May were considered mining at a "loss" although if they held their LTC for a few months they could have sold for at least 10 times it's value when they were mined.
People should think longer-term rather than mine today and sell today. It's not always the best way to be profitable. But to each his own.
