Well if thats the case then your better off buying $200 worth of eth 
Even if it doubles back to $20 in 2-3 months...diff will have doubled by then as well so even more reason to buy coin instead of GPUs.
but GPUs is easy to sell with no big loss unlike asic machines... Even if it doubles back to $20 in 2-3 months...diff will have doubled by then as well so even more reason to buy coin instead of GPUs. They are easy to sell. But there could be big losses if everybody else also want to sell at the same time.
I think it is better not to expand the mining farm now. lets see the effect of the solution to the DAO hack first.
The Ethereum mining difficulty is rising too fast. In the last few months, it rose 40% every month. The price is also dropping.
What do you expect!! All these people that had GPUs and try and make money with them again, then the newbies jump on the bandwagon, not to mention farms that were inactive because you couldn't make squat with GPUs before. If the price keeps dropping people will stop mining because it isn't profitable.
