If you want a good example of doing it wrong look at Release that witch. over 100 Chapters locked @ 9 ss each so almost 20$ just to catch up?
I would be totally fine if the last 2 or 3 chapters of each book was unlocked through SS.
Then if i bought 1000 SS (which i have before). i would at least be able to read all my library'd novels for a month or so.
20$ for a month of reading , its a bit steep but affordable.
Ending up spending that in 1 days catching up on a single novel isn't really affordable though and will just push people away.
Thus less readers = Less people buying SS = failure and can only result in SS being even more expensive than now.
Its like anything if it costs to much people just give it up. said business looses most of its customers and the only way to maintain its income would be to up the prices of everything they sell or get rid of employees.
