1. Do not deposit anything, before your account is not fully verified. Because any bookie will accept your bet without verifying your account, but if you win and request a withdrawal, they will refuse and ask you for verification. You might not pass it for a lot of reasons, like bettors from your country are not allowed to use that bookie, or the documents provided by you are not acceptable e.t.c...
3. Do not be fooled by some kinds of "Super Promotions" like "Place multi bet that will include not less that 4 positions with minimal odd 1.4 and if only one position loose we will return you the half amount of the bet" Multiply bets gives a big advantage to bookmaker because the possibility of win in case of 4 multi bets is equal to 20% or even less. Also avoid any kind of bonuses, because if you will accept them, you will find out that 4 rollovers bets are required to get 100% of offered bonus. Any promotion or bonuses offered by bookmakers are nothing but a way to force you loose more of your money.
