Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it
So you need 30 - 50 GPUs to have 1000 valid WIfs/s ? 
Yes, but you'll need much more if you want to solve it in a reasonable amount of time—though still less than what's required for Puzzle 69.
What will you do if you solve this?
Hahaha, take it easy... It’s not that simple... But... Every member in this topic will get 0.2 BTC—if they have a BTC address in their signature. Satisfied?
