It´s just as legit as question "BTC mooning to 1M USD in the next weeks?" like some clickbait folks do on youtube.
Not exactly. 12-18 months is plenty of time for a rally like 2016-2017 to develop. $250K is completely within the realm of normal when it comes to BTC bubbles too. I think aiming for $300-$400K would be reasonable too based on extrapolations of past moves.
This (speculative) triangle idea is still valid:
That's one route to 6-figure valuations by late 2021 or early 2022. Bitcoin loves to make powerful Wave 5 blow off tops!
