This is what i did i found an offer from a gambling site that says deposit £10 and bet £10 to receive 4000 credits, i set up an account put in the £10 and i bet on a sure thing like an football game that is 2-0 up with 10 mins to get at odds of 1/10.
win the bet get my 4000 credits then withdraw the money.
so now i have £11
i find another offer like a casino that says the same thing i put in my £10 i bet £5 on red £5 on black place the bet win one lose won still have £10 and get my credits. (hope it never lands on zero)
etc etc, i have accounts with every betting site in england due to this game.
now i earn enough from ready to gos where i don't have to do offers any more some days are not good other days i earn 1000 credits, and tbh im not even that good of a player, but i never really lose credits, if you scored 30/60 in all ready to gos you would make a massive profit !
