While its nice to see BR grow, remember UK bookies if not all of them have no law, no morals or ethnics. The amount of times I have seen bookies suspend accounts in uk alone is crazy, its on the uprise too
(I check a few other forums out like SBR )
They won't even transfer your money or winnings back to you, many will just lock it and keep the money and tell you to call the police or hire a solicitor. Don't get me going on the solicitor or police, their even worse crooks then the bookies

Its your call but I would cash out more or if your doing a withdrawal every few months maybe keep it under a limit to 2-3k. Just don't wanna see anyone lose 30k like that guy in the link above.
