Re: why is it not going to $40000

For 1BTC to be 40k USD, something groundbreaking must happen and before that there will be lot of road blocks that need to be cleared. It's possible but game will be getting harder when price climbs up from certain point.

For the price to rise to 40k USD would only require about 40x price increase, we saw a bigger price increase than that in 2013, so seeing this price in the next year or two is not beyond the realm of possibilities. The price might also drop back down to 10, who knows what will happen?

How much did it rise in 2013?

Went from 15 at the beginning of the year to 1000 near the end of the year, that is 67x. If you go by the beginning and end of the year, depending on which exchange you look at, it might be something like 15 to 850, which is 56x. Either way, that is more than the 40x increase we would need to get from 1k to 40k.
