Bitcoin (BTC) is one of the base-layer coins this site reads, and its record comes from its own chain, never from a vendor. Its key here is bitcoin/native.

No grade. No reading of this asset has passed the validation loop yet, so this file carries its record and no grade. A crypto reading reaches production only through the validation loop, with its criteria hashed before the run (rulings 97 and 99).

New units arrive at about 164,362 BTC a year, and the consensus rules cap the supply.

Read at block 971,079 on 2026-10-12, from 2 independent nodes that agreed on that block's own hash.

The chain's blocks were scanned for outages: none wider than this chain's own bar.

It appears here because 13 US-registered products file with the SEC naming it as the underlying: Ark 21Shares Bitcoin ETF (ARKB), iShares Bitcoin Premium Income ETF (BITA), Bitwise Bitcoin ETF (BITB), CoinShares Bitcoin ETF (BRRR), Grayscale Bitcoin Mini Trust ETF (BTC), Invesco Galaxy Bitcoin ETF (BTCO), WisdomTree Bitcoin Fund (BTCW), Fidelity Wise Origin Bitcoin Fund (FBTC), and others.

Every asset has a record. CrossAssetData reads each one from its own source: a company files with the SEC, a network publishes its chain. No price of ours appears on this page, and no grade until a reading passes the validation loop.
