Not at all. That was my balance I think before the introduction of the game. I left the site ages ago and only recently it came to my mind that there I have a small balance. What should I do to get this wonderful tokens?
Ok, that explains it.
Easiest way to get some game tokens is doing the daily tasks.
Top left of the page next to your avatar click "Quests".
Scroll through and see which ones are easy, i.e. "Buy 100 Gift tickets" requires only 200 Crystals (if you buy the cheapest).
That will give you a bronze and a silver chest you can open (just takes a few more Crystals and a few hours to wait), where you then need a little luck, because many but not all chests contain a few trade tokens.
Alternatively you can go to the world, move through the map and look for tokens, as FatFork explained above.
