This is true, many people are caught up in some hype like ICO and Defi which makes them lose a lot of money, especially those who are still unfamiliar with crypto, always following the advice of some friends or family without thinking about the risks and don't know about the project.
They want to make an investment but their money loss in Defi because they only know about the hype, this is sad so to avoid it must learn well before investing and ask advice to friends and family who know about cryptocurrency also so helpful. So don't make a decision until you know exactly about it
