If you buy fifty or more DJCoins then you are entitled to a number of poker chips representing your purchase. It's just a bit of fun and can't be exchanged for anything, but it gives you a physical representation of your virtual asset.
Example 1
If you buy 50 DJC you will receive five 10DJC chips
Example 2
If you buy 79 DJC you will receive seven 10DJC chips.
