It is of course quite easy to setup a Cardano stake pool. You would however also want to understand the math behind the reward mechanism and even more importantly what to do when your nodes need an update or your monitoring tells you that something is not quite running as it should.
The latter requires solid IT skills, especially when folks entrust their precious rewards to you. After all, they assume that you know what you’re doing and also that you know what to do in times of (IT) crisis.
Just delegating is not such a bad option, when you consider the effective cost of owning a pool.
