I see a strange comparison. With current $43k, $20k is closer than $100k. Why not make comparison even? $20k or $63k ? The way from $43k to $100k is much longer and complicated. Frankly, it takes little for the price to drop down. Just one single announcement, even fake one could drop price significantly. But it will take a lot of effort and funds for price to grow.
Btw, this topic was created several years ago, when the price was $60k, and in since then Bitcoin hasnt reached $100k, but managed to drop below $20k. If I was to predict future price now, I would say that it wont go to $100k in next few years. Probably wont go down deeply, but definitely not to $100k.
