Bitcoin in 2021: a mainstream breakout, crossing $67,000 in November, large price fluctuations, over 75% of its supply held by illiquid addresses, and more
Cryptocurrency trader Stephane Ouellette has a special alarm that sounds whenever digital-asset prices post sudden outsize declines.

Context & Ripple Effects
Bloomberg's year-end look back frames 2021 as the moment Bitcoin stopped being a niche trade: it crossed $67,000 in November, won legal recognition in some jurisdictions, and still ended the year with over 75% of circulating supply parked in illiquid addresses. That is a long arc from Bitcoin clearing $10,000 in November 2017 on an 875% annual run — bigger price levels, but per Bloomberg's own framing, still as untamed as ever.
The tension the piece documents — mainstream adoption coexisting with violent drawdowns that force traders like Stephane Ouellette to keep alarms on sudden declines — sets up the cycle the corpus keeps showing afterward: the crash below prior peaks, the January 2023 rebound above $20K, and eventually new highs.
First-order effects
- With more than three-quarters of supply in illiquid addresses, the freely tradable float shrinks at exactly the moment mainstream buyers arrive — small flows translate into outsized price swings, which is what Ouellette's decline alarms are built around.
Second-order effects
- Mainstream status ties Bitcoin's price action to broad risk appetite rather than crypto-native news alone: by the time of the November 2024 rally past $89K, moves in bitcoin were moving Tesla, Coinbase, and Robinhood in the same session, making it an input into equity trading desks.
Third-order effects
- If the pattern holds — legal recognition expanding while illiquid hoarding deepens — Bitcoin settles into a recurring boom-bust-recovery asset class whose cycles reset from each prior peak, with the unresolved legitimacy gap between adoption and regulation defining how far each cycle can stretch.
The trend: Bitcoin is maturing into a mainstream macro asset whose shrinking liquid float amplifies the very volatility its new institutional audience is exposed to.
