In 1st quarter of 2013, the price of bitcoin was $135 so if it was over 286BTC, the calculation would be 286BTC * $135 = $38,610 approx. But the ending price for that year increased to $700.

While for 2018, the bottom was $3,300 and the calculation is 8.4BTC * $3,300 = $27,720 approx. I don't understand the metrics and price range that the chart took if there's a specific price that he has used as basis. And as for 2023 predictions, due to that chart the price of bitcoin obviously increased so what if around 2-4BTC?
