here is an interesting overview by twitter user @sassal0x, published on Nexo dispatch, regarding numbers in Ethereum network in 2017 and 2020, while in both cases ETH price was $500, snapshots are taken on November 29, 2017 and December 16, 2020

one can see from the list that:
- number of active addresses and transactions almost doubled in between
- total number of addresses is 10x up, 24-hour fees changed more than 10x
- development progress soared with over 2000 active developers and over 4 million downloads from Truffle
- DeFi assets changed perspective from millions to billions, stable-coins on ETH changed from non-existence to billions
and ETH2 is introduced with more than 1 billion USD locked-in
after all, price is the same, something is wrong, $500 was too much in 2017, or it is too little in 2020, it is up to anyone to judge for himself, do not take this as financial advice
