Bitcoin data scrapped from BitInfoCharts, without the 'tweets' values.
Several Bitcoin related data scrapped directly from BitInfoCharts. 'date' in the format %Y-%m-%d.
The 'tweets' column was dropped due to too many nan values (values only between 2014-04-09 and 2023-03-14).
Besides, we have only keep the rows between the max(dates with non NaN values of each column) and min(dates with non NaN values of each column), which
leave us with dates between 2011-04-14 and 2024-05-26.
