yes there is always risk to go through an agent but you are risking too if you are sending money to bookmaker.. Bookies want longterm business but also agent know that if they will have more people he will earn more like when he will run with few eur from his first customers..
Sbobet, 188bet and Ibcbet is leading companies in asia.. Every from these 3 bookies have something who other dont have.. for example 188bet have good promotions, sbobet dont and ibcbet id depends on agent if he give you bonus or nor. If you combinate this 3 bookies you will still get the best on the odd world.
Ibcbet offers you more events to bet on also they have more special bets on games like HT/FT etc. They are also good in early market. Also almost on every game you have 2 lines for asian handicap and over/under for FT market and HT market.
The limits are almost same, so you cant have any problem to bet what you want.. One good think of IBCbet is paradise for arbitrage players.. I dont know why but in many times happen that they have better odd than other asian bookies.. many arbitrage players and bonus scalpers will confirm you that they like 12bet (europe ibcbet) but dont like limits..
So If you are serious punter you can use Sbobet or 188bet.. but if you are serious punter and also like arbitrages or you are bonus scalper, ibcbet is excellent for you
Note: Its still better to shopping in 3 (sbo,188,ibc) shops like in 2(sbo,188)
you will get more
