that's a good question.. I think that won't happen before 2025
That feels pretty realistic especially with how the up and downs go in the Bitcoin market. Quite a few mental barriers along our way up.
I would just loosely say "the next bubble". That could be closer to 2020 (halving season), or it could be 2025 or later. I'd bet on the former though, because I think the extremely limited supply will always drive prices up speculatively before adoption goes exponential.
Either way, timing any market is nearly impossible, let alone a market with less than a decade of price history.

Yea like this guy said $100k is possible in the next bull market. Most likely the next bull market will be starting in the next few months and culminate in a peak by end of 2020. I'm not sure if it will actually pass $100k or not at that point but I have high confidence it will reach a bull market peak around $100k (give or take $20k) in 2020. It might take until 2025 for $100k to be the bottom of the market so that the price is stable at $100k+, like how it is $6k now. So very possible we see at least a couple weeks of 6 digit Bitcoin prices in 2020 and then it'll probably be another few years before the price has become stable in the 6 digits to the point in which we don't ever expect to see it below $100k again.
