The data below is from someone who was tracking Ethereum cryptocurrency: number of daily transactions vs price, for 3 months from 1/1/2021 through 3/20/2021. The person noted: "Now, one year ago on 1st March 2020, the number of daily transactions was 628,500. We have now doubled, to around 1.2M daily transactions in March 2021.It is likely that we will at least double that again to 2.4M daily transactions by March 2022." Using this information and plugging it into a regression line using daily transactions to predict price, the person predicted that the price of Ethereum in March 2022 would be $6,414. In fact, in March 2022, the price of Ethereum was about $3,000. (It's currently close to $1,700).

#1: Find the formula for the regression line that this person used, in which he predicted that the price of Ethereum would be $6,414 in March 2022 (there may be roundoff differences).

#2: Why was the prediction so much different from the actual price in March 2022? (please give all the reasons that you can think of).
