### Details

* Native units are considered as sent to an ETF if they are sent to an address we identify as being owned by an ETF.
* Native units are considered as withdrawn if they leave the control of an address we identify as being owned by an ETF.
* This metric is the net of the sends and withdrawals that interval.
* USD metrics are computed as `FlowNet{ETF}Ntv * PriceUSD`

### Asset-Specific Details

* For Bitcoin, this metric excludes the effect of change outputs:
  * If a transaction sends 90 BTC to ETF A but also withdraws 50 BTC from it, the flow is +40 BTC, not +90 BTC and -50 BTC.
