According to Bitcoinist, bitcoin-related tweets have also reached their highest level since October 2018, as bitcoin prices hit their highest monthly gains in May 2019. Joshua Frank, co-founder of California currency analysis company TheTIE, said in an interview with Forbes that BTC had the longest 30-day average amount of tweets since 2017. According to previous reports, the number of Twitter has a strong correlation with the market value of Bitcoin. For mainstream cryptocurrencies such as BTC and ETH, Twitter speculation usually precedes the volatility of currency prices. In May 2019, two of the Bitcoin tweets reached more than 40,000 in 19 days, and there were 19 days of bitcoin tweets exceeding 30,000. During the period from December 7, 2018 to April 2, 2019, there were no more than 30,000 Bitcoin Daily tweets.
