WOW!  Must have bought em at NewEgg last week for $110/ea.  $60 profit on each one, now that the difficulty has jumped, he'll probably do better than using them for mining.

the difficulty jumping is discouraging for mining.  It won't be long before blocks only earn you 25BTC, either.

The 25BTC wont be until sometime in 2012. This is easily calculated based on the fact that only aprox 2016 coins a week are generated. If more are generated then the difficulty is increased of less are then it's decreased. So you'll be safe for awhile at 50BTC. However, I do believe the difficulty will be increasing greatly with all the miners jumping on board. I speculate that once difficulty increases so much that mining isn't worth while for most people they'll be firing down their rigs and selling their components on Ebay. That's what I'm sitting patiently waiting for since all the good components right now are scarce and overpriced. Then when all the get rich quick junkies out there getting out the difficulty should decrease. If that happens then I'll jump into the mining scene. If that doesn't happen then at least I'm not out anything. As of right now it's buying time. I'm just frustrated that there's a 3 day verification for bank accounts on Dwolla or I'd of had 100 coins at around $11 a piece. -.-

maybe i should sell mine...

I didn't know solving a block could earn less than 50 btc.  I thought the difficultly just increased to adjust for the hashing power (~10 minutes per solved block)?

Every 210000 blocks the amount of BTC per block is cut by 50%
