The question is: can i use cubitcrack/clbitcrack or keyhunt-cuda/keyhunt or similar software to brute force a bitcoin wallet like puzzle 66 one? or the asic processors work ONLY with sha256 algorithm?
Aside from my past reply which already mentioned, fon't forget ASIC is abbreviation of
application-specific integrated circuit.
But the question is about pool fairness in general. If I mine solo in a pool (bitcoin pool too) how can i be sure that if i find a block the reward will be sent to my wallet address?
You can't. You need to trust the pool you use.
P.S. Additional question about pool/mining should be asked on new thread.
