I just wasted 15 minutes trying to get in a small Rugby bet.

Odds were 2.80, bet rejected due to "Significant odds change".

Retry at 2.78, bet rejected due to "Significant odds change".

Retry at 2.76, bet rejected due to "Significant odds change".

Took a look out of curiosity, now 2.74

I'm not wasting any more time on this or this site.

Significant odds change!!!

2.80 is 35.71% breakeven.
2.78 is 35.97% breakeven. The significant odds change was a whole one quarter of 1%. Wow!
2.76 is 36.23% breakeven. Same as above.
2.74 is 36.50% breakeven. Same as above.

This is a joke.

I also thought you are the book that allows a player to win 7 bitcoins.
Yet the max here, with the game starting within 15 minutes, was about 1.00 btc, perhaps at most 1.50 btc, in which case your risk is less than 3.00 btc.

We allow players to win 7 bitcoins?
High limits?
