This was a brilliant video. I had to watch it twice.
I think your heading is misleading. He does not say that bitcoin's dominance is coming to an end. In fact I found him to be extremely positive on the future of bitcoin and crypto currencies. What made you choose the title?
He does mention some negative aspects for bitcoin. For example, he says that it will be difficult for the Chinese to deal in bitcoin after the end of October, so they may invest in gold.
About bitcoin, he says "People have lost faith in fiat currencies"
On gold, he says "I would rather invest in a tangible". '
He adds: "Bitcoin is going to have a place in the future, but gold is the tangible that nothing replaces.".
He explains why we hear negative comments from some bankers: "Banksters are going to talk it down, because it is a threat to their business". "It makes the banks obsolete"
"Bitcoin represents the populist movements that are springing up around the world."
Overall, he sees a postive future for both gold and bitcoin, even if he said that he personally prefers the tangible asset.
He says that when gold rises above the high $1400's due to monetary fear, not geo-political crisis, it will blow past $2000.
He said that has never owned any bitcoin. I am pretty sure he just convinced himself he should start buying some so as to diversify away from only gold.
I don't think the title can be edited, but you can always add a small text above the video, like this:
Gold bug still prefers the tangible asset, but says bitcoin has a place in the future.
