I don't know about that. There was this high initial hype around Bakkt, but it was when people were hoping that it could drag Bitcoin out of the bearish market. Moreover, the initial failure of the project probably disappointed a lot of people.
The points about the Google trends algorithms having certain weaknesses that are now exploited seem to make more sense to me.
Oh, and as for that big transaction, it might also be totally unrelated to search results, and the former can be a technical operation by an exchange as people in another discussion thread suggested.
It didn't fail. It was postponed until all the regulatory framework is done and it took a bit longer than expected. About a year longer
There's still a lot of hype surrounding BAKKT because it's a really good project that brings to the space something that wasn't there and that was needed. The mere fact that they were able to get a green light from the regulators shows that much has changed for Bitcoin in the last 2 years.
