If it was 100% certainty that it would stay at that price then 20k - I'm not there yet but assume I will be by the end of the year. Since there is no way to guarantee that it wouldn't just drop back down to nothing right after reaching the peak I'd say more realistically 10K. A $10 price would be too high to not take some gains and given how unlikely that it is that it will happen and even more unlikely that it will stay up that high for an extended period of time, I'd have to cash out some portion of my HP.

It took me a long time to reach 10K though (5 years or something) so I don't think that I'd ever go below that number.
