Not really a good thing to be advertised as the author getting castles of coins. People tend to grow resentful and suspicious of this type of marketing. If it's not made out of bonus coins, it's frigging 100 bucks. Is there a lot of generous whales out there, right? Throwing 100 bucks at novels as if they were confetti.
And... There is another thing that bugs me on it.
I mean, I was really surprised and glad when my novel earned a nice expensive gift (and even more thrilled when a reader sent me my first and generous kofi). But ALL gifts are worthy.
The old 5 coins balloon was worthy. This reader took a part of their little stash of coins to give me out of their generosity. But WN makes it look like only 5000 coins are "worthy".
Not every reader can donate 5000 coins at once.
What if readers start to think their little gifts aren't showy enough?
