Instead of advising newbies to invest in Bitcoin or any other crypto coins out there, just get their curiosity high up by telling them to explore crypto and how it differs from stock trading. People tend to back away from such opportunity when they're almost feel "forced" to. I ain't a psychologist but this is somewhat what I feel whenever people tend to tell me about my decisions about my money.
Do you want them to invest or trade on what they are not perfect off, or you want them to embrace cryptocurrency when they have not known anything concerning cryptocurrency, the thing is that in cryptocurrency you cannot tell someone what to do because investing in cryptocurrency is something of choice and something of determination in which the investors have already map out their plans before coming in, no amount of what you advice them to do that will discouraged them. A cryptocurrency investment is something of choice and mind because if you are not determined you can not invest in cryptocurrency investment.
