Betbull betting exchange have closed down.
Betbull was a great betting exchange with a clean and fast interface.
What very few people knew was that Betbull was another site in another skin.
Betbull was This Great BettingExchange in other clothes. Idea might have been to compete with them selves and test things. What ever happened - probably to little cash flow, a lot of betting exchanges have closed down - Betbull is now closed.
If you liked the odds etc then I recommend that you use the original site - This Great BettingExchange.
I also recommend Betsson betting Exchange as replacement for Betbull.
