title_body: Why is there a 45 Billion coin cap for ADA?
upvoted_answer: Charles Hoskinson stated that it is a fairly arbitrary number in one of his AMAs.
  He jokingly explained,
  
  It's because 44 999 999 999 was not enough, and 45 000 000 001 was too much.
  
  With 1 Million Lovelaces per ADA, there is plenty to go around for the foreseeable future.
