Disclaimer for brave new world: Not financial advice.

Major local Bitcoin peaks followed by meaningful #corrections were:

1. June 2011

2. November 2013

3. December 2017

4. November 2021

5. October 2025 (current local top so far)

I. After June 2011:

* Bitcoinica hack — March 2012 (~9 months later)

* Bitcoin Savings & Trust (Pirateat40) collapse — August 2012 (~14 months later)

II. After November 2013:

* Mt.Gox #bankruptcy — February 2014 (~4 months later)

III. After December 2017:

* BitConnect shutdown — January 2018 (~2 months later)

* Coincheck hack — January 2018 (~2 months later)

* Cryptopia hack — January 2019 (~13 months later)

* QuadrigaCX collapse — January 2019 (~13 months later)

IV. After November 2021:

* Terra / UST / Luna — May 2022 (~6 months later)

* Celsius — June 2022 (~7 months later)

* Three Arrows Capital (3AC) — June 2022 (~7 months later)

* Voyager Digital — July 2022 (~8 months later)

* Vauld — July 2022 (~8 months later)

* BlockFi bankruptcy (although the issues started earlier) — November 2022 (~12 months later)

* #FTX / #Alameda — November 2022 (~12 months later)

* Genesis Global Capital withdrawal freeze — November 2022 (~12 months later)

These were major negative events that followed each new local $BTC peak.

Many of the largest crypto crises historically appeared roughly 6–13 months after market tops.

Disclaimer 2:
this is not a proven causal relationship.
The sample is small, subjective and incomplete.
There were also other major negative events, including the 2016 DAO hack, the 2019 Binance #Hack and others.

V. Since October 2025, there have been no major hacks, bankruptcies or similar events so far, which could suggest (not a signal or prediction) that:

• either hidden stress somewhere in the system still hasn’t surfaced,
• or the market structure has changed.
