That is, in my opinion, impossible to determine. You have no idea which address is a change address, and you have no idea what the objective of a Bitcoin transaction is. Furthermore, no one can count the volume and number of transactions across the Lightning Network.

First of all, when you post such quotes, you have to post the source.
One source I've found is: https://www.blockdata.tech/blog/general/bitcoin-volume-mastercard-visa

Now, while change addresses can be "guessed" in most of the cases, other transactions - like moving from a legacy wallet to a SegWit one may indeed be counted.
But I believe that everything have been calculated, including whale wallet consolidations (they've just for the data from blockchain.com).
Blockdata said a couple words about LN too, but that's off-chain and only the on-chain transactions were counted (so for LN that's only the open/close of a channel, from what I know).
