I heard for it a couple of year ago when there was an whole magazine for PC dedicated to this topic really, from A to Z. I lend it to the colleague of mine who was at that time interested in it...and stupid us neither him or neither me invested in it  Second time it was when Bitstamp become more and more popular and since CEO's and founders are from my country a lot of fuss was around it... Than I decided to take a more time to read about the whole thing of crypto and some time after I participated in first ICO and rest is history....

With colleague we still make jokes on this magazine and what would be if we would invest at that time...but it's easy to be smart now I guess
