The Fear and Greed Index vaguely gives me a hint of temptation

In April, it rose from 40 to a greedy value above 70

The price of Bitcoin rose from 90,000 to 110,000, an increase of 20,000 points.

This time it also rose from 40 to a value above 70

Bitcoin only increased by 10,000 points.

What does this represent? It's open to interpretation, and I welcome discussions from B friends!
