I guess, the investors and swing traders who were constantly monitoring the price also had big contribution to the increased percentage of Google searches. Also, the people who isn't much of a Bitcoin believers and were trying to figure how to acquire and monetize the current price trend.
For sure, It will keep increasing until next year when the halving effect on price subsides.
Anybody already active in Bitcoin's ecosystem doesn't use Google, he/she uses bookmarked pages. Imagine yourself active in cryptocurrencies and so visiting related websites daily/weekly, do you type the keywords daily in the search box or do you save pages in bookmarks to save your time? I guess your bookmarks...
Yeah, I get your point, but If I put myself as an example. I don't visit crypto related websites if I'm on a different device, specially in the office, instead I just simply use Google for a quick check on the current BTC price, because I swing-trade sometimes. Nevertheless, you have a strong point.
To me, the increase in google searches comes from people who start to take interest in BTC or look at it by curiosity because they heard about it in the media outlets, etc. But the most important is does it convert in potential Bitcoiners?
It does, remember a lot of people were trapped purchasing at a higher price expecting more than the $20,000 ATH in 2017.
It may be just people looking to get the BTC price since when you search "Bitcoin" the first thing you get is the real-time rate
Exactly what I meant in my top comment.
