The value of vanity has risen sharply, Reason: it is safe.
Limited vanity sold again does not help the shiny market,Reason: because they are safe, not really want them.
The real solution is:How to revive the market of shiny instead of completely destroying all markets.
I understand what you want, shiny is valued, not to convert them to vanity to preserve value.
I am sorry that my English is not good. I hope you can understand it.
