In order for them to understand fully understand Bitcoin give them some facts regarding Bitcoin let say for example on its price , Bitcoin price back at 2010 was almost zero but over time it successfully managed itself to gain a value as of today almost $1000 in that way they will immideatly understand the value of Bitcoin was the real deal its volatile price will help you to gain profit meaning the early they connected themselves to Bitcoin the larger their profit will be
It is hard for a person who doesn't have an idea with bitcoin at all then one day you'll introduce it to him and tell that it is a good investment that he/she should try it. Of course he will refuse to, let him start first by telling him to read articles about bitcoin, show the market flow for the last 2 years and let him in here in forum.
If that guy live in my country, I can ensure with you that he will never listen to what you say because the media and newspaper have claimed that Bitcoin is the illegal thing and they are trying to prevent the citizen from investing money in Bitcoin. And of course, the government stands behind them
It's wrong to have such approach.
Bitcoin is much more than good investment or possibility to earn good money.
It's revolution, way of life, new way of payment etc.
I will first try to explain ''idea'' behind bitcoin, and that bitcoin is decentralized, without government control, modern tehnology, security etc.
Talk about bitcoin price I will leave for the end.
It's just my opinion.
