Usually there is a direct correlation between the price of each bitcoin and the google trends data. So it's not really surprising that at the height of the bubble where everyone went FOMO buying had the most amount of attention from searches, and right now that trend is cooling off.

To me, that doesn't mean much.

People are naturally attracted to things that they see as profit making, and when BTC isn't climbing up anymore it is easy to see why people gravitate to other things.

Doesn't mean much, just a short term trend. If anything it means that BTC is probably a better buy than it was just a few months ago. Once the next pump comes, watch the trend reverse.
