    "description": "Bitcoin data scrapped from BitInfoCharts, without 'tweets' and with preprocessing.\n\nSeveral Bitcoin related data scrapped directly from BitInfoCharts. 'date' in the format %Y-%m-%d.\nThe 'tweets' column was dropped due to too many nan values (values only between 2014-04-09 and 2023-03-14).\nBesides, we have only kept the rows between the max(dates with non NaN values of each column) and min(dates with non NaN values of each column), which\nleave us with dates between 2011-04-14 and 2024-05-26.\n\nThere are 21 columns:\n\nid_series: The id of the time series.\n\ndate: The date of the time series in the format \"%Y-%m-%d\".\n\ntime_step: The time step on the time series.\n\nvalue_X (X from 0 to 17): The values of the time series, which will be used for the forecasting task.\n\nPreprocessing:\n\n1 - Renamed columns to 'date' and 'value_X' with X from 0 to 17 (number of columns of original dataset).\n\n2 - Created columns 'time_step' and 'id_series'. There is only one 'id_series' (0).\n\n3 - Ensured that there are no missing dates and that the frequency of the time_series is daily.\n\n4 - Filled nan values by propagating the last valid observation to next valid (ffill).\n\nThe columns with some missing values were:\n'median_transaction_fee': 'value_9'\n'confirmationtime': 'value_10'\n'activeaddresses': 'value_15'\n'top100cap': 'value_16'\n\n5 - Casted 'date' to str, 'time_step' to int, 'value_X' to float, and defined 'id_series' as 'category'.",
