Which subnets have more TAO flowing in from chain buys than going out to miners?
Every subnet emits 2,952 alpha tokens to miners each day. That Miner Emission per day you see on taostats is simply 2952 alpha multiplied by the price of the subnet. When Daily Chain Buys exceed Daily Miner Emissions, that subnet is then a net TAO sink. As in, more TAO flowing in than out. It's not entirely accurate or precise, as this ignores TOTAL Net TAO in/outflow. But it's a good metric to look at to see what "the chain" thinks is a good subnet.
So I'm calling this Net Chain Buy Ratio. (Chain buy / Miner emissions).
But not all pools are the same. The Net Chain Buys may affect some pools more than others. So we need to divide the NCB by the pool depth to give us a pool Impact Ratio. Net Chain Buy Impact. (Net chain buy / pool depth).
