I am a big optimist when it comes to Bitcoin, but by the end of 2021 there are only 45 days and it is quite evident that the so-called expert Tom Lee is the closest to completely missing the target again. So I don't see why anyone thinks his speculation is worth considering at all, because it's just one in a series of misconceptions he's uttered over the years.
The key thing is, don't invest based on the speculations of people you don't really know - they all have their reasons for appearing in the media, and it is possible that all three speculations will end up being completely inaccurate.
