Key Takeaways:
- Bitcoin’s 571.2 million user claim lacks public, verifiable evidence.
- USDT’s ~550 million users figure is issuer-provided, not independently confirmed.
- Different methodologies and definitions mean both numbers should be treated cautiously.
Recent claims that “Bitcoin has 571.2 million on-chain users” and “USDT has ~550 million users” are circulating widely. Reviewing issuer disclosures and third‑party analytics shows why one figure is unverified and the other is self‑reported.
There is no publicly verifiable dataset confirming exactly 571.2 million Bitcoin on-chain users; providers typically track addresses and activity rather than unique people. Based on data from Chainalysis, adoption is usually proxied by wallets, transactions, or active addresses, which are not the same as distinct individuals.
By contrast, the “~550 million USDT users” figure is an issuer estimate repeated by media and should be treated as self‑reported. As reported by The Coin Republic, the issuer’s Q4 2025 materials cited about 534 million estimated users, roughly 139.1 million on‑chain holders, and approximately 24.8 million monthly active on‑chain users.
Methodological opacity remains. As reported by KuCoin News, the CEO also highlighted low sender concentration, its largest sender accounted for under 5% of USDT send volume over the past year, which suggests breadth of usage but does not prove unique people counts.
“User” can mean a unique person, a unique wallet, or an account at a custodial platform. On‑chain measures capture addresses across multiple networks, while off‑chain figures include exchange app users and omnibus custodial balances.
Double counting is a material risk when aggregating across chains and platforms, because one person may control several wallets and use multiple exchanges. Exchanges and payment processors can also represent large clusters that inflate “users” when counted as wallets.
For clarity, this article treats “USDT ~550M” as a company estimate blending on‑chain and off‑chain exposure, while “Bitcoin 571.2M” lacks independent corroboration. With that context established, the issuer’s leadership has framed the scale plainly.
“USDT supports over 550 million users globally,” said Paolo Ardoino, CEO of Tether.
Until standardized definitions and third‑party audits map on‑chain holders to off‑chain accounts, these figures should be read as directional rather than definitive.
