I have stayed in the 20 range in the Arena for few days.
Without spending some steem to upgrade my items, I actually went down to the 30 range.
There are many active players who are constantly upgrading their items to stay at the top by purchasing at the market since getting better items at quests or item store can be quite hard.
If you are serious about the game and want to move up the rank, you may just want to find the right items from the market by spending a few steem if you can spare.
