The problem is not the content of the video, crypto or not. The problem is not that YT moderates aggressively (it doesn't do enough IMHO) or even how it moderates. The problem is that there is no serious appeals process, and no third party oversight of moderation decisions. This is true for all the big platforms. How do we fix that, IDK, but probably at the government level.
Yes there is, see [0] - also posted by me in another reply in this thread, where I mention that my own YouTube account was suspended identically to OP earlier this year, but was restored 3-4 hours after filling out the form. The decision may or may not have been AI-driven, but I'm pretty sure there was a human in the loop behind the solution.
Don't mistake me for a Google fanboy - I had my primary Gmail account locked last week for daring to use a VPN, so I'm currently looking at de-Googling myself a bit. But to be fair, I was able to fix both issues within a few hours.
