I'm not Ivan. I started studying this field only last spring and am almost retirement age. For the past 22-23 years I was writing astrology software using my background in astronomy. I first learned to program in Basic in 1977 in high school around the 10th grade but didn't start writing until I was in my mid-late 30's. I first got into bitcoin about 1 year ago and then started following Andreas Antonopoulos.
I was not formally trained as a programmer in college like many people.
