Just before he left, I gave him a serious caution never to give anyone his money with the hope of getting a weekly or monthly dividend, and never to buy and coin that promises to display bitcoin in 3 years as such promising a big price growth. He promised to visit again with his I-pad and diary to start practical class.
Our little exposition of bitcoin and its working principles can help save innocent investors from Ponzi and scam promoters. I never had such opportunity 3years ago, had to read online.
I hope he keeps what you told him in mind, but I'm afraid that it won't stick long. Whenever we enter the next parabolic phase, the most trashy coins keep showing consistent gains, week on week, month on month. The same applies to scams promising high payouts, which they will be able to pay to people because there is enough new money coming in.
It's near impossible for those seeking unrealistic ROI to not get involved one way or another, because they want to buy that dream car/house or whatever.
I remember it myself that I recommended people around me to not put money in x/y/z shitcoin because they have no fundamentals, are scams, etc. Explain people why these coins keep pumping while you are preaching the exact opposite.
