Bitcoin to silver: how much silver does 1 BTC buy?
One bitcoin currently buys roughly 856.61 troy oz. The ratio is recomputed every day at 02:00 UTC from the previous UTC trading day's BTC-USD and XAG-USD spot closes on stooq. The full history is published as a free CC-BY-4.0 dataset at /data so you can run your own gold-silver-bitcoin ratio analysis without an API key.
Silver is the high-volatility cousin in the precious-metals stack. It tracks gold loosely but has industrial-demand exposure (solar PV, electronics, batteries) that breaks the correlation in either direction. Pricing BTC in silver tends to amplify whatever's happening in BTC-USD because silver itself is the noisier denominator.

About silver and bitcoin
Silver is markedly less dense than gold — 10.49 g/cm³ versus 19.32 g/cm³ — so the same dollar value buys a much larger physical volume. The cube renderer on the homepage draws silver to true relative scale; at a thousand-USD position the cube is already palpably bigger than the equivalent gold cube. A US Mint "monster box" holds 500 troy oz; the comparison panel surfaces that as a tile when 1 BTC clears that threshold.
For machine-readable access, the BTC-silver pair is in the full daily dataset at /data alongside gold, platinum, copper, Brent crude, wheat, and coffee. The /methodology page documents stooq's XAGUSD continuous-front-month feed, the cross-validation step, and the forward-fill behaviour on weekends and exchange holidays.
Frequently asked questions
- How many troy ounces of silver does 1 bitcoin buy today?
- About 856.61 troy oz. Recomputed daily at 02:00 UTC from stooq XAGUSD and BTC-USD closes.
- How is the BTC-to-silver ratio calculated?
- Each day's BTC-USD close divided by the same day's XAG-USD close (USD per troy ounce). Both come from stooq spot feeds. Full methodology is at /methodology.
- Is this spot silver or physical bullion?
- Spot. Physical silver coins (Silver Eagles, Maples) and bars typically trade at a 10–25% premium to spot — much higher than gold premiums because silver's lower unit value makes minting/handling costs a bigger fraction.
- How does the bitcoin-silver ratio compare to gold-silver?
- The classic gold-silver ratio has averaged around 60:1 over modern history (more silver per ounce of gold). Compounding that into BTC terms, you can read the BTC-silver ratio off the BTC-gold ratio multiplied by gold-silver. The dataset has both series so you can chart the divergence directly.
- Where does the silver data come from?
- stooq XAGUSD continuous spot. Cross-validated against Massive when both providers cover the same date. Forward-filled on weekends and holidays. See /methodology for full source notes.
