I use keys only to log in without entering password.
So you're not alone.
I had my IP changed several times, my servers are only hosting personal
data.
But I'm still seeing bruteforce attemps in my logs.

Here's something I use on my servers.
In cron, every 5-10 minutes, that should do it.
Of course, if you're running *BSD, pf is way more interesting to do that.

Perhaps could be better to use something standard as fail2ban
