Come back after one year and see how silly you feel after saying that. Or in fact even come back after 6 months if not earlier. Stablecoins are a class of their own, and are meant to be stable. Even fiat currencies see daily volatility, but crypto is known to be at the extremes.
You tell me how much DOGE was 6 months ago:)
You are right, if it's not a stablecoin, it can never be a stablecoin. The mere fact, that Elon Musk tweets were all it took to get Doge running amok is all the fact we need to see, Doge cannot be said to be stable and much so if we take its unlimited supply into account.
