i switched about 90% of my hashpower yesterday from ETH to CryptonightV7 (via Nicehash) since it's so profitable.
reasons for using nicehash instead of monero directly.
1. simplicity is valuable to me, no need to manually trade
2. I try to only deal in coins supported by coinbase/GDAX. Since I'm US based, they're really the only exchange i trust.
3. NH pays me in BTC, which I trade straight to ETH for HODLing.
4. NH is still paying significantly more than mining ETH straight
5* (Bonus for everyone on cryptonightV7) Power use is about 30% lower than ETH! lower electric cost and lower heat all around
you can certainly make more mining Monero straight if you dont mind trading on second tier exchanges (IMO), and the little bit of extra work. Personally I'm more interested in the long term prospects of ETH so that's what im focused on holding and putting my efforts towards.
So you are supporting ETH - the coin that is going to leave gpu miners alone with asics and pos centralization. Rich become more rich ))
You need to invest with your mind and not your emotions. POS actually discourages centralization. Also I am curious how you convert your altcoins to fiat considering almost everything with a fiat trading pair is mined with an ASIC.
