I used to be one of the core testers for this game, as to their previous one, and was invited on their follow up (Pipstycoon, which I declined). Just a little note, to anyone planning on investing in this game:
The guys behind Goldentown, are the same that were behind Anno1777. Anno1777 was quite a successful site with over 50.000
daily active players, yet they managed to reduce that number to less than 1.000. There's quite a story behind that, yet since the site has been sold to a loyal player, I won't tread into details.
Most of the money generated in Goldentown, prior Anno1777 and now also Pipstycoon, ends up in the pockets of a select few. I won't disclose them, yet the pattern is easy to find. There is a certain, well, "business model" behind these sites. Which, made me leave them.
Regarding Goldentown, I can tell you that the claim they are stating that it is backed by real gold, is utterly false.
There is no gold, not a single troy ounce. Never has, at least not in terms of real gold.
My advice, should you plan to invest, is just to be cautious
