I have placed bets on both sports and the casino, but for quick returns, I'd say the casino.
Casino brings quick returns and also easy to make the gambler broke. Taking note of this is very important so that others will not think that it is always wins in casinos without losses because as the money comes so fast, so it disappears from your balance so fast too.
When it comes to sports betting, cricket is fun, but the odds, sessions, and one must be truly genius to know when to place bets!
I have not placed my first bet on cricket but I have read somewhere that it is one of the easiest sports betting to win. I find time to verify that someday and if it turn out to be true, I will start taking it seriously because anywhere money can be made is fine for me.
