i started using bitcoin in 2014 about a year ago. it is around the same date i registered here.
but i have heard about bitcoin much longer before that. maybe around 2-3 years, around the time when everybody was doing solo mining and bitcoin price was skyrocketing through the roof.
the reason that i started using bitcoin was mostly because i liked the technology and idea behind it and also i find trading a great way to earn some extra money.
Bitcoin is 7 years old now and we started one year back we were very late go get into bitcoins. Just imagine if we would have invested at the time of its inception today it would be different stories for us.
