I am using
https://www.mining-dutch.nl solo mining. Monero atm is $322.05. CPU and GPU.
The miners are producing 6000 h/s.
Should I keep the dutch-mining setting to convert to BTC automatically? Or set to keep "if I find a block" hold Monero and not convert?
I understand it could take 6 months to find a block etc.
Not sure about the mining company but whether you want to convert it to Bitcoin or not, depends on your requirement.
Monero has several benefits over Bitcoin. But Bitcoin has higher potential to make you rich. So choose your preferred coin based on your requirement. If you want anonymity, stay with Monero. But if you want to just hold for longer term, choose Bitcoin.
From my personal experience, 6000 h/s isn't much useful.
