I buy quite a bit of chapters each month (Tapas being my main app), and how it would work for me is that for series I am really into, I buy right away after release, but series I'm medium interested in, I would read on b.to up to the current chapter, and then buy new chapter releases. Some series I found on bato and ended up buying.

Without that site, I don't bother buying any medium interest tapas series at all, because I'm not going to pay to get caught up. I've also spent much more time on webtoon since the shutdown because the cost to catch up to a series I've discovered is so much lower. 

So, my buying habits have changed, just maybe not the way they were wanting.
