2. What major event do you think will usher BTC and the entire industry into the next bullrun?
Adoption & Recommendation can work the magic. What is basically affecting the price at the moment is that there is massive panic and a reduced confidence from investors in bitcoin. The price has stayed too low for too long for some, to secure their money many are deciding to sell off more bitcoins with inflation increasing and recession looming. Binance and Celsius fueled peoples panic the more when they recently but temporarily stopped the withdrawal of bitcoin.
If any major country/company can at this point Adopt bitcoin or perhaps a country, an individual who is idolized give some sort of recommendation about bitcoin, that can offer and boost the confidence of investors who are considering selling off not to, and investors who have left or reduced their portfolio to return and increase their bitcoin holding. A series of either adoption or recommendation will get bitcoin pumping again.
