Police in Derbyshire are appealing for information after 18 bitcoin mining machines were stolen from a property.
Eighteen Antminer S9 bitcoin mining machines were taken from West Bars House in Chesterfield in the early evening of March 21.
The force wants to hear from anyone who may have seen people in the West Bars area of the small market place in Chesterfield town centre. In particular, anyone who may have seen people loading items into a vehicle.
Bitcoin is an entirely virtual currency that works without the need for a central bank, and can be sent over the internet.
Coins are transferred directly from person to person, and are kept in a digital wallet that can be accessed on a computer or mobile device.
Creating new coins is done through a process called "mining" where users are rewarded with new coins for verifying transactions that take place.
Bitcoin has its own value and is not tied to any physical currency.
Anyone with any information should contact Derbyshire Constabulary on 101.
