I don't believe it's fair to say that BTC has a 10% yearly inflation. The total supply is 21 million coins that's what Satoshi decided.
If Satoshi released all 21 million coins right away (or at least within the first year), then we would have 0% inflation since the cap has been reached. What difference does it make if the 21 million units are released gradually or all at once (besides the fact that releasing all at once would be terrible).
If I make another btc clone and flood the market with 21 million coins, is it even fair to say that my coin has zero inflation and BTC has 10% inflation?
