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??
You said it all, most people only remember to lament when their friends lose money due to lack of appropriate information etc. Knowledge is power and just like you pointed out, it's wise we educate them on all about cryptocurrencies, the underlying risks etc not just the anticipated profits, so if they are okay with it then they are free to get involved. We should learn to invest only in projects we have studied..
