If people can only use their wallets to make payments or to stake, there's no incentive to run them that often.

However if your wallet has XChat, that is, true P2P instant messaging with end-to-end encryption and IP obfuscation, then you'll use it a whole lot more often. You'll use it every time you chat to someone.

So there'll be larger percentage of XC nodes running at any given point due to XChat.
