Is running an ETH validator node profitable?
I've been hearing a lot about Ethereum and its validator nodes. I'm curious if running an ETH validator node can be profitable. I understand it involves staking ETH and participating in the consensus mechanism, but I'm not quite sure about the financial rewards involved. Could you please explain the potential profitability of running a validator node? Are there any upfront costs or ongoing expenses that I should be aware of? And how does the profitability compare to other investment options in the crypto space? I'm really interested in understanding this aspect more deeply.
