Is mining eth on 2miners via nano payout the most efficient way of accumulating rvn?

I am using kraken exchanges and hold my raven in the exodus wallet.

As much as I would like to already mine raven, with its higher energy consumption and overall lower reward, I decided to instead mine eth on 2 miners and to get the payout in nano on exodus, which I then can exchange for the 1200rvn each month that I would mine, if I were to mine rvn while using the extra ~$30 to save towards another GPU to scale up my tiny mining operation.

Is this the most efficient way of using my resources or am I missing something?
