Kaspa (KAS) is a brand new revolutionary PoW coin that is incredibly easy to mine on a GPU. But are Kaspa mining operations still economically viable and important today? Although mining Kaspa is now less profitable than mining other PoW currencies, it is still profitable. Since ETH mining is no longer possible, Kaspa (KAS) may have very good chances, even if mining has increased in difficulty recently and has become less profitable.
