Okay, I think I'm going to be the one to sort of pop the bubble here. I hate to be "that guy"... but I sorta love it too.
I checked out your comic, and right now you have 16 subscribers. I'm sorry, but in the grand scheme of things, in a world with thousands upon THOUSAND of webcomics, popular and not, saying that your readership is "rapidly increasing over the course of 3 weeks" when it seems to only be at 16 subs is... not profitable. Not in the slightest.
Let me lay it out for you - you will not make an actual profit with the Tapas Tipping program, Ad Revenue, Patreon, or LINE until you break the 1k mark at the bare bones minimum (unless you have a whole lot of friends who are willing to fund you). Even then, your profits will be miniscule. I'm talking $1 every like, 6,000 views (that's about where Ad Revenue's CPM is right now on Tapastic).
I'm at 3.3k right now and you know how much I make? A couple bucks a month through tipping and even less through Ad Revenue. The most I make right now is about $50 on Patreon, and that's after 2 years of updating 4 volumes of content and counting, typically updating 15 pages a week in increments of 3 episodes (Monday, Wednesday, Friday). I'm not bragging, I'm just setting a bar here ... and there are creators who are running multiple series at once right now.
You have 16 subscribers and three episodes. As far as I'm concerned, you're in no position right now to be demanding for "your money" from a free hosting website that is already amazing for offering as many financial options as possible, even if the amounts may only be miniscule for most at best. This is why serious webcomic creators who do this for a living make merchandise, sell physical copies, attend conventions, sell digital E-books, and network the crap out of their stuff. That's all on top of updating constantly with quality content for years, and years, and years. And believe it or not, there are a lot of creators already doing these things but also have to work a full-time job because they still aren't making a living. I don't even know if Tapastic activates Ad Revenue/tipping for series that are as new as yours... in the past they had a prerequisite where you needed at least 500 subs and had to update regularly.
If you're aiming to make a living off this, you're going at it all wrong. Expecting to be making tons of money right off the bat and thinking that your current state is enough to deserve immediate financial gain is just... unrealistic. It might be super disappointing to hear, but I've had to tell this to a bunch of webcomic creators before who thought they'd be making it big (some who even outright quit their jobs thinking it would get them a salary) so you're not the only one I've seen come in here and expect these things.
This is what you should be focusing on right now:
Post to LINE and Tapastic. Two hosts are better than one when you're still new, and seeing as you're still very new, you will need all the views you can get (if making money off your work is your endgame.)
Update consistently. Once a week, twice a week, whatever your schedule is, stick to it. And if you have to skip and update, let your readers know.
Be a voice in the community. Don't just be that random webcomic creator, get to know people, network your work and yourself.
Be patient. There are people I know who've been working on their comics for a decade and still struggle to make a living off their work. Yeah, some people get "lucky" but depending on this chance is like depending on the lottery to get you out of poverty.
You get back what you put in. If you're only updating once a week without any engaging with your readers/fellow creators, networking, or anything that would create a presence for yourself, you're not really gonna get much back (unless you get lucky, but see the above point).
Most of all, be patient.
I'm on my lunch break so I have to go back to work right now, but please consider what I said. You're just not in a position right now where you have to "choose" - both will work just fine for you while you're just starting out. Good luck
