Sorry, I don't agree! I don't see what can be good to burn coins! Maybe I don't understand well...
But many coins will be lost on other ways - for example in lost wallets...
I love that coins are NOT burned, but go as fee from one wallet to another!
The idea is that whenever you burn coins, the rest of the coins become more valuable. This is a way to pay a dividend to all QORA holders.
In this way, whenever someone ran a service that lots of people were using, it would make QORA itself profitable, and these profits would be given to everyone who had QORA coins, because some coins were burned, making the rest of the QORA that everyone held more valuable. Many of the top coins on CMC use this idea: Ripple, Bitshares, NXT, Counterparty. I think Ethereum will as well. Its a great way to provide value to the coin and get people excited about investing in it.
