As recently reported, a popular Wattpad series has been slated for film/television adaptation. This is not the first one.
I have checked out Wattpad as a vehicle for my own fiction. For the present, at least, Wattpad seems to be most useful for YA/romance authors, who write stories about misunderstood teenage girls falling in love with moody, hunky boys (who are maybe also vampires).
Nothing wrong with any of that. But most of my fiction falls under the categories of crime/thriller/horror for adult readers. Therefore, I don't see Wattpad as a good match for me at this time.
Nevertheless, I plan to continue my experiments with posting fiction online, as I did in late 2016 and early 2017 on my YouTube channel.
I have a few new online projects in the works, in fact. More information to follow.
