never is quite a long time! as I noted on a previous thread someone said "why are you here at all-still"
By answering your own question (immediately) shows a closed mind and its a bit sad really. Still, ignoring your answer a more appropriate  view is "never say never". As the depression deepens merchants must cut costs to survive. BTC has almost no transaction fee's and no call backs- its a no brainer- so a few years is my guess. reg
