The three of us started to think about this new development Earning Coins for Paid Stories. You can now earn two coins a day. We took a quick look at the paid stories and what it’d cost to unlock them, and how long it would take for a user to unlock them with earned coins (from watching ads). This is our data (see post #2), we also took into consideration the fact that coins expire after 90 days (3 months): https://www.wattpad.com/earncoins/
We understand WP wants to encourage users to buy coins while also providing this ability for others to earn coins, we think that the expiry period should be increased to long, perhaps a year? And that since chapters are worth 3 coins, that the daily limit could also be three coins. Though since we doubt that is likely to happen, at least increasing the expiry limit since it makes it impossible for some books to be bought at a discount (using video earned coins).
