There's a particular type of "match fixing" fraud I've seen from reading the Trust section of users in the gambling thread (one level up from here). Also have suspected it myself a couple of times. Basically it involves multiplayer poker. It's not exactly match fixing, but if you even have two players colluding at a table with 10, you're making it extremely difficult for the other 8 to win. It's especially profitable when there are more than 1 top prizes for single game.
This is about different, because only the players are involved, but still a very interesting subject. Can you link to some of those profiles? Any idea how did they get exposed?
Sport is popular more then ever, big money circulate in sport and betting on sport attract a lot of people nowadays. Fixing matches and games in sports are nothing new, I'm not sure what crypto currencies have with that. People who fixh matches can pay with money, gold, other goods and now with crypto coins, and I'm sure that some of them use crypto for that.
If a player wants to commit this fraud in fiat systems, he most likely needs to collude with the operator, because it's very hard to hide his identity. But with crypto it's almost impossible to find the person behind the address, which makes this type of fraud much more easier.
The problem with this is that most sportsbookies that accept bitcoin accept only the major games and leagues, and have max. bet or max. wins.
Players playing these matches in major leagues often earn a lot more than they'll be able to win by forfeiting the game when they place a bet.
Would it be worth it for them?
That's a good point, and I guess this means that low tier events can be considered as less safe to bet. Right?
