Bitcoin miner Marathon Digital (MARA) has started mining Kaspa (KAS) to diversify its mining income. Since September 2023, the company has mined 93 million KAS tokens, valued at approximately $15 million.

Kaspa uses a proof-of-work (PoW) consensus protocol called GHOSTDAG, which allows multiple blocks to be produced simultaneously, speeding up transactions and increasing block rewards.

Marathon began mining Kaspa last year by launching its first mining computer. The company purchased equipment for 60 petahash, which can provide a profitability of up to 95%. 30 units are already operating at Marathon's Texas sites, with the remainder expected to be operational by the third quarter.

Many Bitcoin miners are looking for ways to diversify their income after the crypto winter, and Marathon has chosen the strategy of monetizing other layers of Bitcoin to generate additional income.
