Please use another bitcoin fees API provider

Hi, I'm not familiar with your project. I did a search for https://bitcoinfees.earn.com/api/v1/fees/recommended and am alerting projects using this API to inaccurate & old data.

An up-to-date API with accurate data would be https://mempool.space/api/v1/fees/recommended or some alternative.
