Abstract: As the investment properties and financial properties of cryptocurrencies are accepted or recognized by major
listed companies and even sovereign countries, they are increasingly sought after by ordinary investors around
the world. The frantic influx of a large number of investors into the cryptocurrency market has also led to
more and more market analysis and predictions for retail investors and new investors, as well as popular
science teaching videos on the YouTube website. However, their sentiment towards cryptocurrency is not
must be "right". To ascertain the attitude of video producers in YouTube videos towards the market, this article
uses sentiment analysis to analyze the videos and compare the similarity with the Bitcoin fluctuation data
before and after the video upload. We found that in most cases, video producers ’attitudes have a high degree
of similarity with the ups and downs of the period before the upload of the video, but the low similarity to the
trend for some time in the future. This shows that the cryptocurrency-related videos on YouTube merely reflect
past ups and downs and cannot be used as investment advice, even if the video uploaders are doing so.

that time, the official Dogecoin account launched a
vote for the Dogecoin CEO on Twitter, and Musk was

platforms, implying that he will bring Dogecoin to the
moon, and therefore Dogecoin has a "To the Moon"
Slogan. And his series of actions have also attracted
investors' pursuit, and the price of Dogecoin has risen
