Bitcoin Market Cap Surpasses $1 Trillion

Bitcoin's total market capitalization surpassed $1 trillion for the first time in history.

The price move is included because it marked a historically distinctive level or dislocation in Bitcoin’s 2021 market cycle. It is not used as a substitute for the institutional, regulatory or technical events that helped shape market expectations around it.

Placed in the broader 2021 chronology, the event helps show how Bitcoin was simultaneously becoming a subject of institutional finance, public policy, technology development and mass culture. Its inclusion reflects the specific historical development described above rather than a claim that every related market reaction was caused by this event alone.
