The bitcoin historical data from coinmarketcap.com is not displayed correctly from 10 march 2023 and on.

10 march 2023 is a duplicate of 9 march 2023, so all following data is displaced one day. Probably a glitch in the api. Not sure how many visitors depend and the accuracy of the data displayed on your site, but you should probably sort this out asap.
