What did you learn from bitcoin? From your post, I think nothing.
It's curious to see how this people want high price of bitcoin. At first they are looking for low price to buy it, then come here and open threads "bitcoin needs rise" and similar ones, their point is profit. What do you think about stable 20K usd price? You'll come again and say: we need rise... That's boring to my mind, bitcoin goes like it has to go.
It's not the point of the topic. And personally, I agree with the guy. The community learned nothing and keep to be stubborn, the majority will be crying in some times blaming the current banking system
