I think comics made on Eastern countries (mostly Japan/Korea) have a huge advantage over webcomics made on the West.
If you live in Japan and your comic is popular enough, your comic can eventually get an anime, ova, toys, merchandise and all that.
The biggest example i can think is One Punch man. The webcomic started as a good story with terrible amateur art, but because it was popular in japan, it atracted a famous talented mangaka (Murata) to become the artist for the manga, then the anime was launched and it became a global hit. If One punch man was made in a Western country and not in Japan that just wouldn't be posible.
In Korea i think a webtoon called The Sound of your Heart, got a life action tv show. And i'm sure there are others examples.
Western comics, the top know by mainstream media are just those that are owned by the big 2 two (Marvel and DC) and not that famous by the comics itself, but mostly because all the Movies, TV shows, videogames or cartoons. Sure there's some exceptions of comics in other companies like the Walking Dead, Scott Pilgrim, Spawn or Hellboy, but...is extremely rare and only applies to comics made in USA (and most of them have to be in the superhero genre to have success).
For western webcomics you have to cross fingers to see if you've luck with patreon, kickstarter or any other crowd funding stuff, but that's all. It's still on the media of comics, not being adapted to different media.
Just compare how many animes are made based on mangas, with how many cartoons are made by indie comics in the west (and that just probably the ones made in USA). If you live in a third world country where they are no companies betting on comics, then you can only try with webcomics.
