Selling Startup website with huge potential making 1500 usd per month

Why are you selling this site?
I found a new job and can not find enough time to maintain my website.

How is it monetized?
Adsense

Does this site come with any social media accounts?
No

How much time does this site take to run?
2h per day

What challenges are there with running this site?
Writing content for the website is a little bit difficult, but Clash Royale is a new game and its players increasing dramatically.

 

In this picture, you can see the search volumes of words related to clash of clans which is almost the same game with clash royale, both supercell.

And it is clear that "clash royale wiki" has very huge potential

PS: these volumes are only for USA and UK, not global, USA and UK are the best AdSense payers. Globally, "clash of clans wiki" has 200k searches monthly.

My website is in the first page with "clash royale wiki" and "clash royale wiki net"
And ranked better than wikia, ign and other websited in Bing when you search "clash royale wiki"

I made 750 usd last WEEK and I have proof.

 

I don't know anything about the game, how hard will it be for me to jump in and how do you give them the free Gems?
