One hand or Two

I watched a YouTube video where the t showed how he holds his Paperwhite with one hand and uses his other hand to turn pages.

I use my right hand to hold the Kindle and turn pages with my thumb. My free hand only comes into play when I need menus.

Are you a one-handed reader or a two-handed reader?

ps: I have had my Paperwhite 4 and cloth Amazon Kindle cover. I like both.
