Steem treasure hunt 2. Find 0.1 BTC - who will be first?

Hello again. I made already a quiz with 1 BTC a couple of weeks ago and it seems like it was fun. I am sorry, that my funds this time are only enough for 0.1 BTC (https://blockchain.info/address/1A9oCu1bnAtbHfdqeYvko1aQQo3Voud75N) but in exchange its less work. Just find the private key it in my portrait image. If you found it, please tell us, how!

Have fun ;-)
