Online career mode prestige

I just want to know what is the maximum prestige you can get to in online career?? I am currently at 6 with the option of 7 but I don’t want to go any further as everything resets so I’m happy at 6 for now. Can anyone speak any further on this with there experience and if they have gotten further, or is it worth going further. EA is so hard to get ahold of they could answer this simple question
