What to invest 10 thousand zlotys in?

Hi. I have 10,000 zlotys free, which are idle on my account and now I am wondering what would be the best investment? Do you have any ideas? I know it's not very much, but it's better than lying on your bank account and waiting for inflation. I was thinking about gold, but I'm not sure if we can expect any serious increases this year. What do you think?
