I've started mining bitcoins with my Sapphire radeon HD 7850 @ 1025Mhz 4 days ago. I, on average, have a decent hashrate of 300 MH/s. But I want more.
So I'm saving my money up to get a Butterfly labs Jalapeño ASIC miner. As you probably know, it has a speed of 5 Gh/s. I was wondering if it was worth it to order that miner ($300 incl. shipping) in 4.5 months or so. I know I kind of missed the boat since it's mid-2013, but should I?
If I order it in October, what would be the butterfly labs queue? Will the price of bitcoins fall? Will the exchange rate be high, and will too many miners buy the product? Will the mining diff. rise, and make it pointless to mine?

Nice! My average hashrate is 300 MH/s. (Sapphire Radeon HD 7850 @ 1025 MHz)
But I'll only join once you start paying people for mining in the pool. When do you think that will happen?
