which I understand while in the crypto market. no one overestimates BTC. Market movements are unpredictable. but we must know, BTC and other crypto assets grow based on the trust of the community. its value grows based on market interest and growth.
what is the initial price of BTC launched and tradable on the exchange? and how much does it cost now? nobody knew this was happening, and I don't think there's an overestimation here.
So, basically whatever we decide it should be, becomes the new price and that is what public generally thinks about it. It could be overestimated by "some" people, but not generally, because we decide the price with our own money and that is how we make a profit or lose money. Overestimation of bitcoin could technically never happen when you consider how the market works.
