BitcoinWisdom is still one of the best charting sites out there right now
Agreed!
But I'm honestly starting to wonder if
u/BitcoinWisdom has left the project behind to focus on other things
According to his last messages (public and private), he stopped improving the site because he started a complete rewrite of the software. But then he succumbed to the "version 2 syndrome" (which I know quite well...), could not finish it, and apparently his heart was no longer in the project...
Unfortunate. Maybe one day he will either turn the project over to someone else or pick it back up and continue.
