Please stop your whining here if your friend dont know nothing about blockchain and crypto then teach him so he can be independent
Don't let them invest in what they don't know about
how can you invest into somthing if you have no clue about what are you investing in at first place or is just about 21st century beg??
Who are the one who invest on something he did not know about? First of all there are a lot of person want to sure a good money but of course they think twice before they invest. Something gonna bait by scam is a person who experience good before they've scam because most of them become aggressive to learn after they scammed.
Tell about your friend about the good and bad side of crypto for him/her from being aware.
