VISA is a layer 2 solution, it makes no sense to compare it to Bitcoin directly.

Compare Bitcoin to the energy usage of federal reserve and resources spent on securing the US Dollar (implicit and explicit), because that's what the Bitcoin network does. It secures immutable property via a decentralized, open source protocol.

If you want to compare layer 2 solutions, compare Coinbase or Paypal's internal settlement of Bitcoin transactions to VISA. Those metrics are much more relevant.
