That was five years ago when someone introduced bitcoin to me but that was four years ago when I start to involved myself in crypto things. I remember, I am so happy the first time I earned bitcoin. It felt like I am kinda rich or something that I achieved it. At year 2017, I also thought bitcoin price is already high and I can't imagine that after a couple of years it will more higher. If only I bought at least 1 bitcoin five or four years ago then hold it, I am surely a millionaire as of the moment. Well it feels like no one expected this to come and we all learned our lesson. Bitcoin is a very good coin and it is worth holding for a long time.
