Here is some likely nonsense which could use a bit of debunking, if someone feels like doing some analysis: https://www.reddit.com/r/Bitcoin/comments/gngglt/blockchaincom_says_they_account_for_a_third_of/

Had that on my todo list and moved it up a bit yesterday. However, I don't think their claim of '30% of all transactions' is to far off.

Both their low and high feerate estimatimates as well as what properties their online wallet transactions could and certainly don't have is known. For example:

Only spending P2PKH outputs (thus not spending SegWit nor multisig)
Not signaling explicit RBF
Not setting a locktime
BIP-69 compliant (IIRC parts of their wallet are on GitHub, don't have the link handy right now)
Not more than two outputs are created (one payment and maybe one change output)

Applying these filters on my site currently draws 33.50% of the 30.000 loaded transactions. A majority of these follow either the low or high feerate estimates. Obviously, there are outliners. https://mempool.observer/monitor/?filter=RT00JmM9MCZkPTImYj0wJmE9MCZ2aT0xJms9MiZnaT0yJnY9MiZuPTImZz0wJnI9MCZzPTAmdD0wJnE9MCZtPTAmcD0wJm89MCZ6PTAmUj0w

I might start writing this up over the weekend, if I have the time.
