The reading comprehension of dolts is unfathomable. Never did I write "going out of business". What I said is the level of mining (although profitable for those miners) will not be funded sufficiently (relative to the size of the Bitcoin economy) to prevent a 50+% attack because either you penalize transactions (which Bitcoin needs in order to be viable) or you incentivize my Transactions Withholding Attack.
The problem with you novices is you don't understand the issues well enough to even be making any decisions. You are ignorant.
Note I've just put Rassah on ignore (he and LauraM are the only two in my ignore list), so I won't be reading his character assassination campaign and thus won't be responding to it.
Have real work to do it. After much experience with him including he being the first person to call me crazy, I have concluded he presents only 60 Hz noise. Never had I learned one fact or new morsel of information from all of his posts. The low signal-to-noise ratio thus earns him my highest and rarest medal-- an ignore.
