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??
during it can came the profit? why not? experience can make decision about it, maybe people has experience or history about crypto it can make decision for invest so not only focus on blockchain and technology. then beside that you still can learn and read about crypto for youself
