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??
The truth is, this is what have killed or made many people be at lose. The follow what they heard or what they want to hear or what they see someone doing and they feel like it's worth trying. They failed to make the neccessary research to know all that is involved thus when they hit rock bottom they start lamenting.
Also, from another angle most people only share the good news with their friends and families while skipping the risks involved. It's always wise to tell people or make them understand what they are getting involved with so one will blame you afterwards.
