最大ドローダウン期間: Nov 2021 – Nov 2022

約 30 か月で回復
Bitcoin's -80% maximum drawdown means that $4 of every $5 invested vanished. Enduring this period is far harder than it looks on paper.
A 5-year roller coaster: rise → crash → recovery
When it began in January 2021, Bitcoin was around $30k per coin. It then rose to an all-time high of about $61k in November 2021.
But from 2022, a crash began as global tightening and a broad collapse of the crypto market (the Luna implosion, the FTX bankruptcy) piled up. In November 2022, Bitcoin fell to about $12k, recording an -80% drawdown from the peak.
Someone who kept up the ~$37-a-week investment during this stretch continued buying Bitcoin at very low prices. In 2023–2024, expectations for a Bitcoin ETF and the actual approval (January 2024) combined with the halving effect, and Bitcoin set a new high in March 2024.
After 5 years, the estimated value is about $46k (pre-tax) — roughly 4.8 times the total of about $9.6k invested.
Could you have endured -80%?
The key question in this story is not "+377% over 5 years." It is "could you have held on in 2022 when your account was down -80%?"
At some point during the ~$37-a-week investment, your account balance falls to about 20% of the invested principal. In that state — "will I still put in another $37 next week?" — most people could not.
Bitcoin plays by different rules than traditional financial assets. Its correlation with the stock market has been rising, but it carries risks that stocks do not: regulatory risk, technology risk, hacking risk, and more. This service does not recommend investing in Bitcoin.
