I'm not a fan of "to da moons" and even less of "bitcoin is dead" but just a friendly reminder. It requires 12mil people out of 7bil (like 0.2% of whole population) to buy 1 bitcoin each to run out of bitcoins, or 1.2mil people to buy 10 btc each. And I know people who are buying in bulks, like me. The rest you can imagine yourself.
