I don't recommend friends around me to leave the market because there are still many ways to make money, but I don't recommend my friends to buy cryptocurrencies immediately, because the spread of the bear market will bring them unpredictable losses!
You are actually pushing your friends away from becoming rich in the future. It is a time when the price of all the coins are very lower and we have to buy as much as possible. Buying in this time is the same as early investors and in the long term the price will grow much higher.
