for me my favorite altcoin is Dogecoin. because Dogecoin really helped me in making transactions from one market to another because of the very low transaction fees. and now Dogecoin has found its newest ath this year, and this is an extraordinary achievement in my opinion, because Dogecoin which is considered a coin meme has been able to find the newest ath at this time.
If DOGE is your favorite coin, then you my friend are a fool and should rethink your life and investment decisions.
DOGE has no real use, and as such is unsustainable. Even XRP has more fundamentals than DOGE
