I like Benjamin Cowen's analysis on BTC. He goes through different ways of modeling whether it's overvalued and favors a more data driven approach. He's done a few videos on the subject but this one summarizes it well, although a bit long it's well worth the watch: https://youtu.be/zW6Ktg0GygE
The short term TL;DW, we of course don't know what will happen for sure but most likely we'll probably see a correction within the next day/week/month, but in the long term the data shows 100k BTC within the next 3 years.
More than likely it will fall off massively very soon. Right now a lot of people are jumping in on the bitcoin craze like they did before because of fomo and not because of any real value they see in it. I think overall bitcoin is still crazy undervalued but it will also likely have a huge drop off soon.
