There is a big difference between 20k and 180k and people will always ignore that in the end. When you go from 100 dollars to 20k you are talking about a market cap increase from around 2 billion dollars to 370 billion dollars, that is a huge 368 billion dollars increase and I think many people would fail to see that, if they did we would had a lot more people selling those days (even though there was a ton already).
However when you talk about 180k, that means the price is lets say 10k right now, it means market cap going from 1.85 billion dollars to 3.315 trillion dollars. TRILLION , as in 1000 billion. If you think they are the same thing you are kidding yourself, there is no world going from 100 dollars to 20k dollars is similar to going from 10k to 180k, the amount required is nowhere near the same, we are talking about 10x times bigger.
You can post many reasons, but deep in your heart, you know you would NOT believe that Bitcoin will surge to $20,000 if the question was asked during 2012. I would never believe it too.
It should be a hard lesson learned for us.
