Shiba Inu and Dogecoin are back on watchlists this month. SHIB just passed 1.8 million addresses across Ethereum and Shibarium (U.Today, September 12), and DOGE still holds a  $15 billion market cap after a rough week. The investors who made money on those two the first time know the math, though. Shiba Inu carries a $3.08 billion market cap and Dogecoin $13.12 billion, so a 10x from here needs tens of billions in fresh buying. The bigger returns now belong to whatever is sitting where SHIB sat in early 2021.
