Aliens TLDR

Those would have been the ones that staked while prices were below current levels.

The majority staked while ETH was priced between $2,500 and $3,500 according to the chart.

The chart only shows staking entry prices and does not account for the additional rewards in ETH, which are currently around 4.2% APY.

However, the chart only shows the price of ETH at the time of staking, not at the time of purchase, so those figures could be skewed somewhat.

When the Beacon Chain went live at the beginning of Dec 2020, ETH was priced at a little over $600 as reported at the time by Be[In]Crypto.

A final crypto capitulation could push Ethereum prices down to levels where all stakers are in the red.
