https://youtu.be/x0LqsUOIw0M I re-uploaded it here, I'm just sure that some quality has been lost but it was the best I could find.
If someone had the original in the best possible quality, I have another clue about a wallet but in the current quality it is not possible to decrypt it.
Yes, the video quality is not very good. I have been trying to find the last key for a year now, without success. In the video you can see that some places with clues are covered up and I can't see them.
