Betting on Ethereum is never a wise idea since they moved to PoS last September.Since then the activities and the price of Ethereum has not been a lot and most of the time this coin looks stable without much investors support anymore,at least not from guys like us who love the PoW coins much more.For Bitcoin which will never go PoS and this is as sure as death is for everyone of us,we can bet on the price as a lot of market factors can influence its price with lately being the rate hikes of different central banks or when a big huge firm start some involvement with it,while for Ethereum since going PoS I highly doubt one great firm will be investing in it.
