Yes. Since 2014, Dogecoin can be merged-mined with other scrypt-based blockchains. Thus, its hashrate was strongly dependent on Litecoin miners for several years. This changed with the Dogecoin frenzy in early 2021, when the cryptocurrency became one of the most profitable to mine. Not surprisingly, this attracted many new miners, who wanted to profit from this opportunity. As a result, Dogecoin’s hashrate has strongly increased and even surpassed that of Litecoin. You can merge mine Dogecoin when your mining iBitHub (iBH) since it is a scrypt-based proof-of-work blockchain.
