Let's first see the total amount of ETH that has been staked with Lido up to this date.

So there are the total of 3.96M ETH that staked with Lido, which is very close to what DefiLlama shows as the staked ETH amount.

Now let's see the daily amount of ETH that staked with Lido in past 3 months.

We see the chart starts from Mar 16th where there was around 47k ETH staked. Approximate average of daily ETH staked on next 3 days was around 50k, but after that, we see the amount of staked ETH went down to about 5k. There were few days on Apr that the number of ETH staked went up to about 20k but didn't stay there and went down again.

On Apr last days and starting days of May we see the amount of staked ETH shows some spikes. May 2nd is the day that with 104.16k has the highest amount of staked ETH on a single day over past 3 months.

After May 11th we see the amount of staked ETH dropped heavily and since then the amount of ETH staked on Lido was below 1k for most of the days. The reason for this could be that the Curve peg broke so users could get more stETH by swapping there rather than staking directly.
