$25 profit is ~100 STEEM that could will be worth $1000 if when Steem goes back to $10.

As it stands now, he has $90,000 worth of Steem power invested. Assuming he is/could get a straight job (which seems rather likely), it would be easier and less time consuming to come up with an extra $25 in a month using overtime pay than the amount of time it would take to setup a Steem node. It's no different if he gets it from rewards or from trading it is still 100 Steem.
