Recently, some relatives visited me and they were investigating if I had invested as I am quite active online. I lied to them because I see no point in arguing with them.
Some people are not open minded in this kind of investment like your relatives they are not believe in bitcoin, don't arguing in this kind of person cause it useless they don't understand you and bitcoin. You can't blame yourself to lied them and quitely work in bitcoin.
Yeah, there is no point on arguing as they are closed minded now and will never understand you. Maybe he just need to wait some good timing and soon he can finally prove to them that they are all wrong.
