The page How Chrono Coins Work is a wonderfully designed page. It’s simple, informative, interactive, and easy to read.
Since the site changes when the coin streak was removed, the other changed feature was that when coins are added when a real daily deal store purchase is made.
Perhaps you can include this little extra bit of information in there?
Or perhaps this is completely superfluous and everyone can find out when they purchase from the daily deal, but this will just add a bit more visibility to that.
A mere suggestion, definitely not high priority.
