The Ethereum gas price is currently about 6 gwei, the lowest I've seen it in a very long time. It was over 100 gwei most of the time for over a year I think.
However daily transactions on the network don't seem to have decreased much at all. There are still about 1 million to 1.2 million transactions happening per day according to https://etherscan.io/chart/tx.
What is the difference that is causing the gas price to be lower now?
