Hello to all here!

I am glad to find a coin named gold-coin... There are so many crypto coins.. It was difficult to choose one in what I am interested in...
I don't know much about cypto coins and I know nothing about mining them.
Maybe someone can help me a little bit to understand.
I red that mining with the wallet is very inefficient - but I would like to try, just for fun.
But I am not sure that it works.
My wallet told me it has about 500 Hashes/s, 10 active connections and it's up todate.
But in the debug-log I see for example:
trying connection 178.221.56.76:8121 lastseen=1,8hrs
connection timeout
trying connection 89.152.17.230:8121 lastseen=21,2hrs
connection timeout
trying connection 94.78.177.204:8121 lastseen=69,0hrs
connection timeout
What's wrong? Am I mining or not?
My settings are 4 Threads, Scantime 99. What does this mean and should I change it?
Thanks for any help!
