I got it now. Your goal is that if someone wants to use bitcoin over TOR, they can exit at your node. You aren't running bitcoin on this computer, you're just allowing traffic to exit.
Yep, that's it.Quote
I think I understand now and sorry for the confusion. 
No probs, could have been my non native english style of writing ;-)Quote
I'm not too clear on the use case for that, because if I want to send a transaction anonymously, can't I just use a tor http connection to broadcast the transaction on, say, blockchain.info's public api?
Probably you could, but life is all about choices ;-)
And mainly I'm running these ports as an exit because I hope to get marked as an exit node (without having much extra risk) and therefor have a chance of collecting more bitcoins because I'm listed at oniontip
Running the node (with a very shitty connection) as a relay for a few months didn't get me *any* satoshis (altough there were donations to others).
I hope to increase my chances by getting the exit flag and increasing my bandwidth a bit.
Like I said, it running on a spare google TV stick and is consuming a few watts (likely less than 5 watt)
I would love to have some satoshis collected this way, only for the fun of it.
