It's true that our friends speak bitcoin without learning it first, they just talk, after I explain about bitcoin, they accept it and many want to learn in the forum.
Only few of my friends really listened to me when I explain to them about the bitcoin and some cryptocurrencies like ethereum and ripple. They are willing to invest some amount they are still hesitants because of the risky nature of crylto investing. I told them to learn more about crypto trading before pursuing their plan to invest. Other friends didn't believe in cryptocurrencies, considered it as a scam or just a waste of money.
