I remember when i told one of my closest friends to invest in this coin, he trusted me and decided to put $1000 into it, a single one only.
2 months later the price dropped 100 times cheaper (from 1k sats to 10 sats) his investment turn from 1k to 10 bucks. He was so upset and decided to stay away from crypto currency  .
I never told anyone to invest into anything from then on.
