Stablecoins.
Dollars with extra steps and counterparty risk.
Tether (USDT) and USDC together hold over $200 billion. They are called stable but they carry real risks. This page explains how stablecoins work, where they fit, and why Bitcoin holders are skeptical.
A stablecoin is a crypto token designed to hold a fixed value, usually $1. It solves volatility but replaces it with counterparty risk: someone holds the backing assets, and that someone can freeze your account, fail, or lie about their reserves. Useful infrastructure for short-term operations in the crypto ecosystem. Not a substitute for Bitcoin in long-term savings.
Section 1 · What stablecoins are
A stablecoin is a cryptocurrency designed to maintain a stable value relative to a reference asset, almost always the US dollar.
Why they exist: crypto markets are volatile. Traders and users wanted a way to stay in the crypto ecosystem without holding volatile assets. Stablecoins let you move value quickly across blockchains without converting to bank accounts.
Fiat-backed
Holds actual dollars or short-duration Treasuries in reserve. Examples: USDT (Tether), USDC (Circle). You send $1, you get 1 stablecoin. The issuer holds $1 in reserve. Redeem the token, get $1 back. Risk: trust the issuer actually has the reserves.
Algorithmic
No reserves. Uses algorithms and incentive mechanisms to maintain the peg. Most famous failure: TerraUST/LUNA collapsed in May 2022, wiping out approximately $40 billion in value verify×DON'T TRUST, VERIFYClaim: Terra/LUNA collapse in May 2022 wiped out approximately $40 billion in market value.Verify at: CoinGecko Terra Luna Classic page ↗Market-cap loss can be reconstructed from CoinGecko/CoinMarketCap historical data. SEC enforcement actions document the timeline.. Most algorithmic stablecoins have been discredited or failed.
Crypto-backed
Over-collateralized with other crypto assets. Example: DAI (MakerDAO), backed by Ethereum and other crypto at over 100% collateral. Risk: if the underlying crypto falls sharply, the system can become undercollateralized.
Section 2 · The scale
As of 2026 stablecoins represent over $200 billion in market capitalization verify×DON'T TRUST, VERIFYClaim: Stablecoins represent over $200 billion in total market capitalization as of 2026.Verify at: CoinMarketCap stablecoin sector ↗CoinMarketCap and CoinGecko both maintain live aggregate market-cap data for the stablecoin sector..
- Tether (USDT): the largest stablecoin, issued by Tether Limited based in the British Virgin Islands.
- USDC: issued by Circle, based in the US, with more transparent reserves and US regulatory oversight.
Section 3 · The risks most users miss
Reserve risk (USDT specifically)
Tether has historically been opaque about its reserves and has settled multiple regulatory cases over reserve misrepresentation verify×DON'T TRUST, VERIFYClaim: Tether settled enforcement cases with the CFTC and the New York Attorney General over reserve misrepresentation.Verify at: CFTC Tether settlement (2021) ↗ · NY AG Tether/Bitfinex settlement (2021) ↗Settlement documents are public on each agency's website.. Tether now publishes quarterly attestations, which are not full audits. The unresolved question: does $1 of actual dollar-equivalent assets back every USDT? If not, a bank run on USDT could cause a cascade failure.
Freezing risk
Both USDT and USDC can freeze individual wallets. Tether has frozen wallets at law-enforcement request. Circle froze USDC wallets connected to Tornado Cash after OFAC sanctions in August 2022 verify×DON'T TRUST, VERIFYClaim: Circle froze USDC wallets connected to Tornado Cash after OFAC sanctioned the protocol in August 2022.Verify at: Circle statement on OFAC action ↗Circle published the freeze decision publicly.. This is a fundamental difference from Bitcoin: no one can freeze your Bitcoin wallet.
Regulatory risk
Stablecoins are under active regulatory scrutiny in the US and EU. Potential outcomes range from licensing requirements (the EU MiCA framework took effect in 2024) to outright prohibition of certain issuers.
De-pegging risk
Even fiat-backed stablecoins can lose their peg in market stress. USDC briefly de-pegged to $0.87 in March 2023 when Circle disclosed $3.3 billion in reserves held at Silicon Valley Bank during its collapse verify×DON'T TRUST, VERIFYClaim: USDC de-pegged to $0.87 in March 2023 due to SVB exposure of $3.3B.Verify at: Circle update on USDC and SVB ↗Circle disclosed exposure publicly. Historical USDC price data confirms the de-peg trough..
Section 3b · The rewards economics under GENIUS and CLARITY
Two pieces of US legislation define what stablecoins can pay you in 2026 and who can pay it. They are not symmetric, and the asymmetry matters.
Signed July 2025. Defines a federal payment-stablecoin framework. Bans the issuer from paying interest or yield directly to stablecoin holders. You hold $1 of USDC at Circle: Circle owes you $1 back. Circle does not owe you a cent of yield on the $1, even if it earns 5% on the Treasuries backing your token verify×DON'T TRUST, VERIFYClaim: The GENIUS Act of 2025 prohibits permitted payment stablecoin issuers from paying interest on stablecoin balances.Verify at: Congress.gov: GENIUS Act ↗The bill text is publicly available. Confirm against the enacted version (PL 119-XX) before quoting the exact statutory citation..
Passed House 2025; Senate version under negotiation as of May 2026. Sets digital-asset market structure. The active fight: whether affiliated platforms (Coinbase paying USDC rewards via its partnership with Circle; exchanges paying "loyalty yields" denominated in stablecoins) can do what the issuer cannot. Industry wants the exchange-rewards lane open. Consumer groups want it closed under the same logic as the GENIUS issuer ban. The outcome of that fight determines whether US-resident stablecoin holders can earn ~4% on USDC balances in 2027.
Where the spread actually goes
Compare the economics across three structures. The denominator is the same: short-duration Treasury yield around 4.5% in mid-2026.
| STRUCTURE | YOU EARN | INTERMEDIARY KEEPS | CONSUMER PROTECTIONS |
|---|---|---|---|
| Traditional bank | ~0.05% checking, ~3.7% HYSA | ~3% net interest margin (NIM) | FDIC $250K, OCC supervision, CRA lending |
| Stablecoin issuer alone | 0% (GENIUS ban) | ~4.5% full Treasury yield (issuer pockets the entire float) | No FDIC, federal stablecoin charter |
| Stablecoin + affiliated platform rewards | ~4% (if CLARITY allows it) | ~0.5% (thin) | No FDIC, exchange-broker disclosures only |
| Self-custodied USDC in your wallet | 0% (no eligible counterparty) | N/A | None, you hold a token, not a deposit |
The structural read: banks are not worried about self-custody stablecoins eroding deposits. A self-custodied USDC pays nothing. There is no rate competition because there is no counterparty to pay. Banks are worried about custodial stablecoin platforms (Coinbase, Kraken, similar) where the user holds USDC on the platform and the platform routes ~4% rewards to compete with HYSAs. That structure has no FDIC, no capital requirements, no CRA lending mandate, and no exam cycle. From the bank lobby's perspective, that is a deposit-flight pipeline disguised as a digital-asset feature.
The alignment with Bitcoin self-custody
A philosophical observation that emerges from the law: rewards only flow when you are not self-custodied. Hold USDC on Coinbase, eligible for rewards (if CLARITY allows). Hold the same USDC in MetaMask on a hardware wallet, zero rewards, no counterparty. The yield is a payment for being part of someone else's balance sheet. Bitcoin self-custody is the same trade in mirror image: zero yield, zero counterparty risk, full sovereignty. If the goal is escape from the rehypothecation chain, the "no rewards" outcome is the feature, not the bug. See the sovereignty stack.
Section 4 · The Bitcoin perspective
Bitcoin holders are generally skeptical of stablecoins for one fundamental reason: a stablecoin is a dollar with extra steps. You hold a dollar. You exchange it for a token that represents a dollar. The token is controlled by a centralized issuer who can freeze it, who may or may not have the backing they claim, and who operates under government jurisdiction. If you wanted dollars, you could just hold dollars.
The use case stablecoins fill (moving value quickly across crypto rails) is real. The Lightning Network fills a similar function for Bitcoin payments without counterparty risk. See Lightning Network.
The honest position
- Stablecoins are useful infrastructure in the crypto ecosystem.
- They are not sound money and they are not censorship-resistant.
- For long-term savings, stablecoins are not a substitute for Bitcoin.
- For short-term operations in the crypto ecosystem, they serve a real function.
- In countries with collapsing currencies (Argentina, Nigeria, Turkey), USDT and USDC compete with Bitcoin for the role of dollar-substitute. Both are used. Bitcoin's exit is more complete; stablecoins are more accessible.
