The supply of bitcoin is just too great for it to rise to such a high level, and it probably wouldn't happen as there will almost certainly be a coin that supersedes Bitcoin and has some kind of better encryption.
SHA256 will only be secure for a few more decades, so unless major work is done on the platform by then bitcoin may fall behind other coins.
This is someone who understands a little bit more about the incredible number of assumptions that are in place for a 1 milliom dollar bitcoin value!
Although to be fair, efforts to improve the platform and advance it technologically can only work to further boost the value of btc.
Yes, the above two comments seem the most realistic. There are too many variables (re the future) that we cannot know, including many variables that we cannot predict (similar to those trying to predict Black Swan events).
While my guess is that BTC will do great in the medium-term (say 3 - 5 years, maybe reach $10,000 or even $25,000), I would be reluctant to predict much further out than that. There is always the possibility of a better coin, even with Bitcoin's first mover advantage.
$1,000,000 per BTC, would that value be in hyper-inflated dollars?
