I did some analysis and have come to understand that majority of us are afraid to tell people about bitcoin because people see it as a scam and maybe, it could implicate us. But then, I think I know a good way you can convince them that bitcoin isn't scam.
You could simply bring out a dollar (or any fiat you have in your pocket) then ask him/her what that is. For sure, 'money' will be the answer. Then ask him this simple question; "if someone happens to scam you and take all your dollars, does it mean that dollar is a scam?"
Or, you could rephrase the last line to; "does it mean that dollar was made for scamming people?"
Try to be very polite when asking such questions. Try to make them understand that everything that has a use has a misuse too. Be descriptive!
They need to understand that bitcoin is simply a currency like Dollar, Euro, Cedis, etc. (except for the fact it is a digital currency).
I believe that was helpful.
Yes it is very easy to say that on a crypto people like us or to the crypto enthusiast in which it was very easy to explain it to them and for them to understand it so fast because they already know what cryptocurrency is, but the thing is if they are open-minded enough to absorb what cryptocurrency is all about or they already made up their mind to built an understanding talks with you because until that the people doesn't have the courage to listen with you then they will just ignore you at the end of the day.
