The study looked at the Bitcoin bubble in 2019. They found two major bubbles in 2017 and 2019. The first bubble was caused by a rise in ICOs, while the second was influenced by the release of Libra. They used the LPPLS model to predict when the bubbles would burst. In 2019, the bubble burst quicker due to government regulations and hedging assets. Holding onto Bitcoin for a longer time was more beneficial in 2019.
