In many ways, Gems are a Bitcoin equivalent in that Gems serve no value transfer function that Bitcoin does not already serve.

The purchase of Gems provides a transitory buzz bonus, although a theoretical bitcoin review buy in could be made to provide the same bonus.

Bitcoins are fungible.  Gems are nonrefundable and nontransferable.  

Why is the procedural advantage of the stops involved in the purchase and spend of gems.  None.
