I asked if its troll post because he has bigger activity on forum than I do (so one would expect he lerned something by now),
and he also claimed to study computer sciences in another post
Wow

Thanks.
I didn't really study his background before answering. I always think that if I don't help the poster, maybe I help others that search for the same topic. And with this price of Bitcoin, I expect many to try to mine alts and sell for Bitcoin...
Still sad to see trolls in action when many others have good intentions..
