Only 44.6% of the bitcoins BTCC sealed are still sleeping.
Where these coins come from
Four things to know before reading the numbers.
An exchange’s mint
BTCC Mint was the numismatic arm of BTCC (formerly BTCChina), China’s oldest exchange. The coins were designed and produced under its CEO, Bobby Lee.
Titanium and fresh bitcoins
“Spacecraft-grade” titanium or solid silver, loaded with never-circulated bitcoins taken straight from the block rewards mined by the BTCC pool, hence the “Bitcoin Block” coins worth ~25 BTC.
One seal, one key, one choice
The private key is sealed under a tamper-evident hologram on the back. Peeling the hologram off means recovering the funds and destroying the collector value. Every coin is verifiable on-chain through its funding address.
A permanently closed supply
Minting stopped in 2018, when BTCC was sold. No coin will ever be produced again: availability can only fall, one broken seal after another.
Availability by series
Share of the print run still sealed, i.e. still available in collector condition. The best series are the ones nobody dares to open.
Where the remaining BTC sleeps
Area ∝ BTC still sealed in each series, compared at a glance to the grey hatched block: everything that has already left the metal. Of what remains, most sleeps in titanium.
The Grail matrix
Surviving population (log) × survival rate. Bubble = sealed BTC. The top-left corner is the collector’s dream.
Denominations
From a thousandth of a bitcoin to a whole block (~25 BTC) struck into a coin. The bigger the denomination, the more seals have popped: the survival rate collapses as face value climbs.
The minting chronicle
Coins funded per month (bars) and BTC committed (line). Two stories: the flood of chips in late 2016, and the value peaks of summer 2016, halving included.
