Recommended bookmakers and how many?

Hi, I have been trying RB for a few days now with 2 swedish bookmakers and already got a ROI of 70% but I would like to get more bets so I was thinking I should use more bookmakers but not realy sure wich?

Bet365 seems to be impossible to acces from time to time, what du you guys recommend?

What do you mean that B365 is impossible to access from time to time? Most of the time there is no issue to access B365.
