1. A considerable amount of coins have already been mined and a significant amount will be minted. Anything over 20-30 million coins is way too much and will dilute the value of any coin. When a coin has a total supply of 18+ billion the coin is pretty much doomed. Over time Doge and other coins will also suffer because too many coins are in "circulation".
I disagree and I think you are dumb. A coin that has 18 billion + will just have holders holding millions of coins. A coin with millions of coins will have holders holding thousands of coins. There is zero difference and to pretend that having more total coins makes a currency more or less valuable is borderline retarded.
