Guys, let me tell you the future of sports betting.
By future, I mean after 20 years!
Let's Back to the Future!
Pregame Betting

Your bets won't be accepted instantly. Every bet will be accepted via operator/system. All bets will be checked (if line is value or loose, if there's a line movement) before accepted.
This way, they will prevent value hunters and arbitrage traders.
Live Betting

All bets will be accepted after a period of waiting (aka periof od danger) just like asians book. Let's say Ronaldo is behind the ball, getting ready for freekick. Your won't be accepted instantly. Your bet will be accepted when ball is out of play. (or rejected if Ronaldo scores a goal)
Live arbing will become extremely difficult.
Account Verification

Books will take your fingerprint for ID verification. They will make KYC verification via Skype Video Chat. They will visit your adress via Google Earth/Street and will decide if account owner is a real person. This way, they will prevent arbitrage bettors and bonus hunters who open accounts (with ID) for beggars and truck drivers, lol.
Arbitrage Betting

Bookmakers will come up with ridiculous withdrawal fees. They will enable free withdrawals for only recreational players. Bonus offers will exist only loser, recreational playes. E-Wallets will increase transaction fees. Soft bookies will get meaner, they will detect if you're an arber and will limit you after 1st bet. With Period of waiting, they will push live arbers out of business. Arbitrage Betting will no longer be a business where you can win a million in 2-3 years. Arbitrage traders still exist but their income will be decreased dramatically. Books who are slow to move lines and reaction will still exist but most of these books will be scam and they will confisticate your money.
Pinnacle

Pinnacle will be still restricted in USA. Sorry fellas.
SBR

SBR population will reach 10 million. JJGold will still be posting.
Natalie Rydström will be anchorwoman in CNN.
