People who consider bitcoin to be too expensive don't understand bitcoin, and even if they end up buying on the dip, they will end up selling way too much too soon.
I think this happens more to newbies. Maybe after getting an idea about Bitcoin, they think the current price is expensive after seeing the past price of Bitcoin. Actually, Bitcoin has never been expensive, Bitcoin has not been expensive in the past and Bitcoin is not expensive in the present either, because the price of Bitcoin will not remain stable here, but rather the price of Bitcoin will increase a lot over time. Now those who think Bitcoin is expensive should gain proper knowledge about Bitcoin, because if they do not have proper knowledge, they will not consider Bitcoin trustworthy. You have to invest in Bitcoin with trust and hold it.
