Relax people ETH PoS will not happen, postponement is the only way forward for Ethereum and also Ravencoin can not be mine with another coin in dual mining mode because ravencoin on its own puts lot of stress on GPUs and takes lot of power too.
As i written.
And yes i say it since last year that we not seeing ETH 2.0 this year or next year. Vitalik must test this shit on Dogecoin first.
