I see there's a lot of competition in the area, is there a comprehensive list with comparisons somewhere? Google searches suggest https://cryptoradar.co. Source: over 2 years ago

In terms of comparing rates - coin gecko works pretty well. Apps like cryptoradar and cryptolens can be useful for helping break down the rates associated with each exchange aswell (a exchange might have a good rate, but charger a marker taker fee in the end). Source: about 3 years ago

If instead you have a cohort on hand — -i.e., you do not want to send your data to a third party for any reason, or perhaps you have energetic undergrads — -then you could alternatively consider local, open-source annotation such as CVAT and Label Studio. Finally, nowadays, you might instead work with Large Multimodal Models to have them annotate your data; more on this awkward angle later. - Source: dev.to / about 2 months ago
