Within a year or two, I think. With the caveat it might also drop to zero.
I agree, if bitcoin doesn't fail and drop to $0, it will absolutely reach $1000, and almost certainly reach $10,000.
$10,000?!?! Really?? That would take a very long time....
Why would it have to take a long time? Who would have thought going from 1 to 100 would only take a couple years? Why would going from 100 to 10000 take longer? The network effect starts to kick in and the adoption accelerates, so the rate of price increase goes up. Bitcoin could hit 10000 tomorrow, all it would take would be for people to pull the asks below that and raise the bids.
