I would encourage friends to understand blockchain and encryption currency, but it is not a good investment opportunity, because the bear market has come, I would suggest they learn more knowledge, so when the bull market comes, everyone will make money.
Of course, I will tell my friends and explain to them how crypto works. So that the have idea and its up to them if they would join us. Because its better that they know that, this not a scam but although some smart people make this as opportunity to earn by scamming other people. So that they will be aware which is scam and real crypto business.
