I heard the bitcoin first time from the internet in 2012 but I did not pay much attention to it, I was so shocked to know the price of about $ 200 in 2014, at that time I started paying attention to this bitcoin development and I am very grateful to know bitcoin because it increases my income per month.
It was similar for me. I heard about it when it still wasn't very popular but it took me a while before I realized its potential.
