I knew about Bitcoin 2 years ago when the price was $500. I wasn't really into it but my friend told me about it. My friend had to return me some money which he paid in bitcoin. It was just 0.03 BTC. My friend started selling his BTC for 20% less than the actual price. I was still skeptic about BTC  so I didn't buy from him. Today I sometimes think about it and regret but then again every experience is lesson. Money comes and goes.
