Single post in Shiny Sink (similar to Doug on PF1)

I think converting shinies straight into gp or another currency is a big nono. Some form of chance still has to be involved, otherwise why would I want to bother trading shinies if I can immediately get a guaranteed amount from doug? (unless the reward is even lower than the so-called low market prices) Maybe the daily limit should be even steeper than before, say, you can only turn in 5 pokes per day
