So far my experience

2. restaurant owners telling me...they are invested in crypto currency although they admitted they know nothing about it...and said its a great investment

one guy who was selling stones and such things (street vendor) he was hyper and said he's about to quit that business and retire soon coz he's all into crypto

Anyway, be careful even if it's free

Here's what Buffett the king money manager recently said about crypto currency

Buffett won't talk anything like this publicly unless he's certain..Now don't tell me he's wrong and you're right.
