$BNB
BNB Binance Coin cannot be mined because all the BNB coins have been pre-mined at its launch in 2017. Although the coin does not operate on a Proof-of-Work (PoW) consensus protocol like Bitcoin, the only exception to mining the Binance Coin is through a mining software called unMineable. This process allows you to mine coins that are not PoW, and you can later switch them to your preferred asset.
