I honestly started looking for bitcoin 2013 and in 2014 I started giving up until finally I got nothing. but when bitcoin soared in 2017 I started again. from that I thought not to procrastinate anymore. because in my opinion there is more even though a little is important don't give up.
Lesson learned. You have found a gem earlier than most of the people here but you let the opportunity pass and slip in your hands.
Though many things had happened for the past few years, believe me we are still early adopters.
It seems to me that in 5 years, many will look at bitcoin and think why I did not dare then to make a contribution to the cryptocurrency. And those who took the risk will be delighted... So I would risk and buy or earn cryptocurrency right now.
