No one will be interested in running an eth node when taking your analysis into considerations but if we look at it the other way round we could conclude this way:
32 eth @ $190 = $6k, profit for the year 0.5 eth = $90.
The price of eth is predicted to hit $1000 by next year ending.
32 eth @ $1000 = $32,000, profit for the year 0.5 eth = $500
The choice is yours/ours.
Yes this could happen.
There could be more who will doing the staking taking the demand higher.
Also, an example would be sharing for the stakes. Let us say I will buy the 16 ETH while my partner will take the other half.
There are a lot of possibilities for profit.
But as tinyteapot says it, it is your own choice. If that is how you calculate everything then do not go further.
But again, the possibility of ETH going back to its ATH is also possible which makes the profit higher.
