  1. You’ve falsely stated KSI’s net worth to be only $15 million. That’s straight up incorrect. KSI’s net worth is $20 million. You can literally just google “KSI net worth” and it would tell you that. 

    How would his net worth be only $15 million ? KSI literally confirmed in MensHealth interview that he owns 10 properties in England with combined worth of over £10 million. That’s over £10 million ($13 million) in properties alone so how would his net worth be only $15 million ? That makes no sense. 

    You’re literally the ONLY website that has put that low of a number in KSI’s net worth and its straight up false. Correct the error as soon as possible.

    You’ve also stated in that article that “It is reported that KSI annual salary is $1.12 million.” which is again false, that was his earnings back in 2014, he then earned $4.5 million in 2015 and $11 million in 2016. And it has only gone up since then. It doesn’t take much to research all that, its literally all given on his wikipedia page with all sources attached.
