How this service works
Probably Lost Supply — The estimated supply of "zombie" BTC, coins that have been inactive since the launch of the first BTC exchange in July 2010. Patoshi-mined coins are included in this category. Data by Glassnode.
Output
Returns a time-series array of objects, each with a Unix timestamp (t) and the estimated probably-lost BTC supply value (v), representing coins considered permanently dormant since before July 2010.
Example use cases
Analyze lost Bitcoin in portfolio risk
“I'm doing a report on effective Bitcoin circulating supply for investors. Can you grab Glassnode's probably lost supply metric — those zombie coins dormant since 2010 — and tell me what percentage that represents of the total supply? I need the latest number.”
Track historical zombie coin trends
“Show me how Glassnode's estimate of probably lost Bitcoin has changed over time. I want to see if the dormant supply figure has stayed constant or if new data has adjusted their zombie coin estimates.”
Compare Satoshi's unmoved coins
“How many of the Patoshi-mined coins does Glassnode include in their probably lost Bitcoin estimate? I'm trying to understand how much of Satoshi's original mining output is still sitting inactive.”
