Bitcoin is a high-risk investment, so it is very risky for people who do not have the basic knowledge to buy bitcoins, especially if they think that investing in bitcoins is a get-rich-quick scheme, it is best to tell your neighbors not to rush into the market if they don't want to lose everything and also tell the person to understand the risks related to bitcoins first and learn how to store bitcoins safely after buying bitcoins, because basically bitcoins are also vulnerable to hacking besides the price is very volatile.
