The approval of spot Bitcoin ETFs in January 2024 marked a pivotal shift in the digital asset landscape — and at the center of the storm stands Grayscale’s Bitcoin Trust (GBTC). Once the largest institutional gateway to Bitcoin, GBTC has transitioned from a price driver to a source of short-term selling pressure. As its shares convert into tradable ETF units, billions in Bitcoin holdings are flowing out. But how much further will this outflow go? Who are the key sellers? And what does it mean for Bitcoin’s long-term trajectory?
This analysis dives into the mechanics of GBTC’s outflows, breaking down shareholder categories, estimated exit volumes, and the net impact on Bitcoin’s market dynamics. While short-term volatility persists, the eventual digestion of this supply overhang could pave the way for stronger fundamentals ahead.
The ETF Shift: Net Inflows Amid GBTC Outflows
On January 25, 2024, the U.S. Securities and Exchange Commission (SEC) approved multiple spot Bitcoin ETFs — a landmark moment for crypto adoption. However, the immediate aftermath saw Bitcoin prices dip, contrary to bullish expectations. Why?
The answer lies in GBTC’s structural transformation. After years as a closed-end fund with limited redemption options, GBTC became an open-market ETF, enabling shareholders to redeem their shares for actual Bitcoin. This triggered a wave of selling as investors exited the high-fee trust.
In the first nine trading days post-approval:
- Over $4 billion worth of Bitcoin flowed out of GBTC
- Approximately $5.2 billion flowed into competing spot Bitcoin ETFs
Despite a net positive capital inflow of $1.2 billion across all ETFs, Bitcoin’s price declined — highlighting the localized impact of GBTC’s concentrated sell-offs. The market isn’t rejecting Bitcoin; it’s digesting a temporary imbalance between supply release and new demand absorption.

Understanding GBTC’s Role Reversal
From 2020 to 2021, GBTC was a bullish catalyst. Due to regulatory constraints, many institutions couldn’t buy Bitcoin directly. GBTC offered exposure — and traded at a premium to its net asset value (NAV), sometimes exceeding 40%. This premium incentivized arbitrageurs like Three Arrows Capital (3AC), Celsius, and BlockFi to buy BTC and convert it into GBTC shares for profit.
But when the 2022 bear market hit and redemption remained restricted, GBTC flipped into persistent discount territory — sometimes as deep as 25% below NAV. This discount became a structural drag on Bitcoin’s price, encouraging strategies that involved buying GBTC while shorting BTC to capture convergence.
The collapse of Terra and subsequent bankruptcies accelerated forced liquidations of GBTC shares. Entities like FTX, Genesis Global, and unnamed distressed funds were left holding undervalued shares with no easy exit — until now.
With ETF conversion, these dormant sellers finally have an exit ramp.
Who’s Selling? A Breakdown of GBTC Shareholders
To forecast future outflows, we must examine who holds GBTC shares and their likely behavior:
🔹 Bankrupt and Liquidating Entities (15% | ~80,000 BTC)
Holders include:
- FTX: Sold ~20,000 BTC worth of shares in the first 8 days
- Genesis Global: Holds ~32,000 BTC equivalent
- One unnamed entity: ~28,000 BTC
These entities are legally obligated to liquidate assets to repay creditors. Their sales are not strategic — they’re mandatory. Most of FTX’s holdings have already been sold; Genesis and others are expected to follow suit rapidly.
Outlook: Nearly 100% of these shares will exit, likely within weeks. While disruptive in bursts, this segment represents a finite and largely predictable overhang.
🔹 Retail Investors: Brokerage & Retirement Accounts (50% | ~255,000 BTC)
This group includes individual investors who bought GBTC through platforms like Robinhood or Fidelity.
Brokerage Accounts
- Sales depend heavily on Bitcoin price performance and capital gains taxes.
- If BTC rises, investors may hesitate to sell due to tax liabilities (15–35% capital gains).
- If BTC falls, more holders may sell at a loss to avoid further declines.
- Conservative estimate: 25% may exit, influenced by market sentiment.
IRA (Retirement) Accounts
- Tax-exempt accounts are highly sensitive to fees.
- GBTC charges a 1.5% annual management fee — six times higher than competitors like BlackRock or Fidelity.
- These investors can switch ETFs without triggering taxes.
- Estimate: Up to 75% may migrate to lower-cost alternatives.

🔹 Institutional Investors (35% | ~180,000 BTC)
This category includes hedge funds, family offices, and arbitrage players.
Arbitrage Funds (e.g., FirTree, Saba Capital)
- Held GBTC to exploit the discount vs. spot BTC.
- Strategy: Buy GBTC + short BTC → profit when spreads converge.
- Post-conversion, this trade is unwinding.
- These players are likely to exit entirely in cash, not reinvest in BTC.
- Estimated exposure: ~130,000 BTC at risk of permanent cash conversion.
Native Crypto Funds & Whales (~5%)
- Likely to rollover GBTC shares into other spot ETFs or hold BTC directly.
- Minimal net selling pressure — just a portfolio rebalancing.
Crypto-Native Investors (~5%)
- May exit GBTC to rotate into altcoins or stable assets.
- Mildly bearish impact, but not significant.
Projected Outflows and Net Market Impact
| Category | Estimated Outflow |
|---|---|
| Liquidating Entities | 55,000 BTC |
| Retail Brokerage | 65,000 – 75,000 BTC |
| IRA Accounts | 10,000 – 12,250 BTC |
| Institutional (Cash Exit) | 35,000 – 40,000 BTC |
| Total Projected Outflow | ~135,000 – 230,000 BTC |
Combined with prior outflows (~115,000 BTC), total expected outflow reaches 250,000–350,000 BTC.
However, not all outflows equal selling pressure:
- 150,000–200,000 BTC expected to flow into other ETFs or held as BTC
- 100,000–150,000 BTC projected as net cash exits (true sell-side pressure)
As of January 26, 2024, about 115,000 BTC had already exited, suggesting 30–45% of total outflows have occurred. The remainder is likely to unfold over the next 20–30 trading days.
FAQs: Addressing Key Investor Concerns
Q: Why is Bitcoin falling if ETFs are approved?
A: While ETF approval is structurally bullish long-term, GBTC’s conversion created a short-term supply shock. Billions in shares are being sold by distressed holders and fee-sensitive investors — overwhelming initial inflows into new ETFs.
Q: Is all GBTC outflow bad for Bitcoin?
A: No. Only the portion converted to cash creates downward pressure. Funds moving from GBTC to lower-cost ETFs (like IBIT or FBTC) represent portfolio rotation — not reduced demand for Bitcoin.
Q: How long will the selling last?
A: Most outflows are expected within 1–2 months. Bankrupt estates will liquidate quickly; retail and institutions will follow gradually. After this period, GBTC-related pressure should ease significantly.
Q: Could this lead to a market bottom?
A: Historically, forced selling events often precede rebounds. Once the supply overhang clears — especially before the 2024 halving — renewed demand could drive strong upside momentum.
Q: Will GBTC disappear?
A: Unlikely. It will likely stabilize with a smaller AUM base (250K–350K BTC). Its brand recognition and liquidity may retain a core investor base despite higher fees.
The Path Forward: From Pressure to Opportunity
The current phase is best described as orderly deleveraging. GBTC’s dominance is fading — but this transition strengthens the broader ecosystem by distributing Bitcoin exposure across multiple competitive ETFs.
Once the outflows settle:
- Fee-driven migration will end
- Distressed selling will be exhausted
- New demand from ETFs will dominate price action
With reduced internal friction and growing institutional adoption, Bitcoin may emerge from this cycle with stronger fundamentals than before.

While short-term volatility remains inevitable, the long-term outlook grows clearer: the end of GBTC’s monopoly could mark the beginning of Bitcoin’s next maturation phase.
