Youtube research is a nightmare. I am trying to use 'site:youtube.com bitcoin' in Google, and customising the date range, but there are so many false positives.<p>I have this one (15 nov 2010): https://www.youtube.com/watch?v=AiGCuyRJe8s. But not sure this is THE first one.<p>Is there a good technic to properly search Youtube videos ?
