I'm in doubt.
I got the BTC I invested very cheap. So if I get the BTC back I've invested in the chip and 50% of the money invested in a Bitburners I would be even already because of the current BTC rate.

But like Roy, I'm actually not looking for profit, I'm just in it for fun.
I would be satisfied if I just get a ROI. And correct me if I'm wrong, but even with the rising difficulty this should be possible, right?!

Not if you dont find a special way to mine. The diffi is not only rising exponentially, the prozentual rise is exponentially too. Thats not a good sign.

Could you help me out there? What percentage?

If you are asking about rising difficulty percentage, then it is about 30-35% every about 13 days(75-85 %/month).
Also difficulty rising percentage growing all the time while BitFury devices has gone online(atleast 107 ghash,https://ghash.io), Avalon delivered some chips(i think at least 25T) and BFL seems to get something out, new Asic manufacturers are going in before end of 2013 (November,October,December). Currently in January at least BitBurner 20 will use more power that get bitcoins(http://mining.thegenesisblock.com/a/acb725f391).
