The fee does go towards hosting the campaign page. Also GiveHongBao doesn't charge for the deployment of the campaign contract--- that is paid out of my own account, so charging a small nominal fee felt fair to me.

I think an interesting point is to compare the fee to what GoFundMe and other similar sites are charging.

My motivation was mainly to make a competitive version that took advantage of Ethereum's native advantages:

- It's Global. You can use GiveHongBao anywhere in the world. You can't use GoFundMe unless you're in the western world

- It's direct. Your donations go straight into your wallet. You don't have to wait for a minimum donation size, nor do you have to wait for a certain time.

- It's cheaper. Ethereum transfers are a flat fee regardless of size (vs. credit card processing fees). I thought a fair thing to do would be to mirror this and charge only a flat fee (for hosting, etc..) then pass the savings on to campaign creators.
