Up to 2 Million Bitcoin Sit Idle Behind a 32% Tax Bill, Sypher Capital Finds
State of Bitcoin Yield 2026 maps six holder segments as basis yields slip under Treasuries and on-chain incentive TVL drops about 74%
JERSEY CITY, N.J., Sept. 09, 2026 (GLOBE NEWSWIRE) -- An estimated 1.5 to 2 million bitcoin bought below $5,000, on the order of $135 billion at current prices, sits idle because a sale would hand roughly 32% of the position to tax. That tranche is the largest pool of bitcoin not earning yield, according to The State of Bitcoin Yield 2026, a paper released today by Sypher Capital and BorrowOnBitcoin.
Bitcoin yield should not be judged by headline APY alone, the paper argues. Fit depends on the holder's cost basis, where the coins sit, and who pays the return: a borrower, an options seller, a token treasury, or the holder's own upside.
Bitcoin's Early Yield Engines Have Compressed
Behind that argument is a steep re-pricing across the strategies that once paid double digits:
| Yield engine | At its peak | August 2026 |
| Bitcoin basis trade | More than 20% annualized (2021) | Below the 2-year Treasury every month since February 2026 |
| Bitcoin implied volatility (covered-call income) |
Above 90 (February 2026) | Mid-30s |
| Incentive-driven BTCfi TVL (Layer- 2 and sidechain programs) |
October 2025 peak | Down roughly 74% from peak |

Institutional bitcoin-income products have recently arrived. BlackRock's iShares Bitcoin Premium Income ETF (BITA) began trading in June. Goldman Sachs agreed in August to acquire NEOS Investments, manager of a bitcoin covered-call ETF, for up to $2.25 billion. The paper treats that as a maturing market: when capital scales into a strategy, the spread tends to fall.
Six Bitcoin Holder Segments
| Customer | Est. size (Aug. 2026) |
Cost-basis profile | Primary need |
| Sub-$5k holders (whales and early adopters) |
1.5–2M BTC | Pre-2018; >90% embedded gain |
Keep the coins; avoid a taxable sale |
| $5k–$30k holders (2019–2021 class) |
~1.5M BTC | ~55–90% embedded gain | Yield without giving up title |
| $30k–$65k small retail | 0.5–1M BTC | 2024–26 buyers; modest gain |
Rate, simplicity, low minimums |
| $30k–$65k large retail / HNW | 0.5–1M BTC | Modest gain; large portfolios |
Rate plus tax, legal, accounting support |
| ETF holders | 1.3M BTC | ~$80,000 average | Convenience; yield was never on the menu |
| Institutions and treasury companies |
1.4M BTC in treasuries |
Mixed; often elevated | Mandate-clean income at size, with audit |
| Sizes are Sypher estimates from onchain cohorts and disclosed holdings as of August 2026, order-of-magnitude. | |||
For the sub-$5,000 cohort, yield is useful because it defers a taxable sale. ETF holders have little in-wrapper yield beyond lending of the shares themselves.
“Bitcoin yield is moving from a search for the highest rate to a search for the right rate,” said Steven Han, Partner of Sypher Capital. “What a product pays matters less than whether it fits the holder's basis, custody and the source of the return.”
