There are various good options for folks like you. I’d naturally recommend an approach where you have a good return for your ADA (ROA) and at the same time “Make the world work better for all”.
In this light, you could have a look at ASTOR. It is a non-profit pool run by professionals. On top of what you get elsewhere (with pools of similar size), you could enjoy our monthly extra payments as documented here and here. Some other good options are here.
If you should need help with the technical details of delegating, we can do that too. For now, lets just say: Delegating does not involve sending ADA anywhere (that would be a scam).
