I show them my portfolio. I show them the Bitcoin price drop and rise patterns. They have their jaws dropped after seeing my results with cryptocurrencies.
I have a lot of friends who hate bitcoin so much, and this is what I do I showed them my portfolio and give them some coins to spend it. I believe those who hate bitcoin have never bought bitcoin or used it before. But I don't know why most nonbelievers are come from the banker or financial institution.
When I encounter with non believer I will just show him the proof of my earning, I will explained to them how much I already earn by showing them the date I made my wallet and the price chart when the first time I knew bitcoin, I will try my best to make them understand but if in the end, they dont want to hear or accept, then I just ignore them, btc is the golden chance to make huge profit, if they hate bitcoin then its their lost
Well actually we don't have to do this, it's all up to them whether to accept bitcoin or not. we cannot be harmed by doing this.
