Why don't token prices actually change, both in the YouTube video and now?

If you look closely at the Uniswap and Kyper values in the video, they are the same for each iteration

I get the same results locally as well. Different numbers but they don't change over time.

The Infura.io project endpoint is set to MAINNET, so why am I not seeing live data?

Good catch, it's the same for me.

As I have gotten more familiar with this topic I think this may be the answer: I was initially under the impression that the number we were seeing was supposed to be the frequently fluctuating cost of a coin. However within a liquidity pool, ones token price is relative to the other and fluctuates as liquidity amounts change, which is less frequent.

Is that the case?
