Ergo looks like the main competitor of Ravencoin in terms of mining, which one do you think it's more valuable to mine and keep for future? What do you think about Ergo project?
Don't waste your time with those coins, they consume the double of energy than the Eth protocol, next coin for mining is ETC.
1) ERG(autolykos) consumes ~15% less than ethash and ~40% less than kawpow
2) I'm not really following the oracle solution that ergo provides for cardano, but it could have certain potential... I guess, assuming ADA has bright future
