It's not only about Bitcoin but also about many different assets. People tend to buy Bitcoin even though they don't understand cryptocurrenncies or they don't even bother to read about them. People panic right now because its price is constantly decreasing without any particular reason. Don't focus on the price, focus on the technology.
most people I know just bought bitcoin because they don't want to miss out if the growth like in 2017 happens again. They don't care about te technology or idea behind it at all
