I've been wanting to gather information on Bitcoin's historical mempool size (per day), but unfortunately I haven't been able to gather any sources that give the complete history of Bitcoin's mempool size. So far, the best source I've gotten is from blockchain.com, which only shows the stats from 2016-2020 when blocks started becoming full. I want to gather as much information as possible about Bitcoin's historical mempool size. Ideally, the information should span from 2009-2020, but if it starts in 2010 or 2011, that's okay.
Apart from the information itself, it needs to be in a format that is easy to copy and past such as csv, xlsx, or even a normal text table that can paste without formatting issues would be good.
