Along the same lines as Dyme,
Quyd or Qyd
Again a one syllable word. And a homonym of quid, hinting at value (at least to Brits :P). Rhymes with "vid." The letters in Qyd could be easily adapted into a stylized logo and smartphone app icon.
Googling, there is an old band from Germany named Quyd but I doubt there would be any trademark issues.
If this name isn't selected please create a British football betting site.
sQuyd or sQyd you could even have a squid mascot.
