Sequentially, BTC drops by period were:
2011: -93%
2013: -86%
2017: -84%
2021: -75%
2026: -50%
Conclusion: As BTC matures, it becomes more stable, and the declines are increasingly smaller. We'll probably never see a decline again for values below $70,000. In the future, the decline will likely be less than 40% for values above $250,000 or $300,000. Enjoy.
