No this is a big misconception in my opinion. It may be the case at bookmakers like SBOBet, Pinnacle etc. who have fewer markets and higher liquidity (but I'm not sure as I never worked for one). I worked as a trader and it was extremely rare to end up with a balanced book like that. We did sometimes move the odds slightly based on liabilities but we never wanted to move them so much as to arb with the wider market.

>Why don't they just use those people to adjust their odds faster for everybody else ? Or do they limit the size you can bet rather than just banning you ?

Some of them ban outright and some restrict your stake. When I worked for a bookmaker we had an account that had made several hundred thousand £s from us and was limited to betting relatively small amounts. He would always bet as soon as our odds would open and then we'd adjust them.

Could you not just bet with the Asian bookmakers? (sbo, pinnacle, ibc etc.)

Isn't that exactly what genetic drift is?

Exact same thing happened to me and I decided not to snowboard again, the risk just isn't worth it to me.

Also I was wearing a helmet but I don't believe they will prevent concussions?

Some bookmakers (Pinnacle, Sbobet, ibcbet etc.) do just that and their odds are controlled by the amount of money being bet on either side of the handicap, but it's a completely different model and most bookmakers don't have the liquidity to do this.

I worked as a trader for a UK based bookmaker and in reality it wasn't like that. You were betting against the house and it was very rare for us to make money on any outcome.

>I had to turn them up so high when outside with normal street noise that they gave me a pretty terrible headache.

You have to be really careful doing that. It's very easy to screw up your ears with bone conduction headphones if you try to drown out background noise by increasing the volume.
