In a recent research on Google trends and Twitter, it has been found out that the number of tweets and their corresponding sentiments can influence prices. The research ultimately reflects that Bitcoin price trends reflect crowd psychology.
Per the research, 21 million bots on Twitter, posted information about spam, advertisements, prices, etc. Moreover, the researchers have found out that Twitter sentiment is positive in nature even in the wake of falling prices.
However, despite their findings researchers have incorporated sentiment analysis using different techniques.
Researchers have used open source VADER (Valence Aware Dictionary and Sentiment Reasoner) for analyzing tweet data. Furthermore, tweet data dating back to 2014 using the site bitinfocharts.com. Google trends data (SVI) was also taken into account.
