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.
You gave him the best word existent in the world, Bitcoin is a dominant force but it is not a get rich soon scheme.
If you get further opportunities, i implore you educate them more.
The next time he visits you again, tell him the types of wallet he should use and how to store the keys privately, in case he decides to hold bitcoin on the long run for himself.
Education is the key to avoid false hopes from potential crypto users. Learning crypto is not an overnight one. It would take time for someone to fully grasp the ins and outs, but if he is willing to learn, time is not an issue. We should always be honest when we want someone to deal with crypto. Because with false introduction, that's where people are getting the negative notion and consequently, doesn't want to deal with crypto anymore as they thought it is a fraud.
