Unlike Bitcoin, Shiba Inu (SHIB) cannot be mined on its own. Instead, it can be obtained through an unmineable pool. There are no publicly traded companies that are primarily focused on mining SHIB. However, there are a few companies that accept SHIB as a form of payment, such as AMC Entertainment, Newegg, and Nordstrom. Additionally, there are companies like PBN Builder Kings and DuckDice that may have some association with SHIB, but they are not primarily focused on mining it.
