I am no means a coin developer, but I was thinking...  When the change to update wallets to DGW3 is done, could it possibly be looked at reducing total number of coins? (maybe not at DGW3 update but sometime in future update by someone). 
If total number of coins now will be 2 billion to exist (if feel the coin will always remain undervalued/priced as there is just too many) I understand the original intent of 2 billion to be different/unique.. but the core values of the coin is what makes this unique already, a charity coin.  I was thinkng if coins were reduced by a factor of 25, so total # would be 80 mil not 2 billion (this will also help increase value and rarity of the coin).  I know alot of work would need to be put into doing something like this (and I do not have the coding/skills needed to even attempt this).  Figured I'd throw this out there and see what others also think.   
Again thank you owlhooter for taking a look at this coin and helping to improve upon it
