BittterCoin is an old calculator machine hacked to be used as a miner validating the pending bitcoins transactions in the Blockchain (Online distributed data base). BitterCoin combines Internet of Things, media archaeology and economy. The operations are displayed on the calculator screen and printed afterwards. The Bitcoin was originally conceived as an electronic decentralized system for capital transactions. Each node (user) has the same opportunities to get a reward when validating a transaction. In the last years this system has triggered in a competitive struggle in which computing power is the most important variable for earning Bitcoins. This involves the use of large equipment, computers farms spending physical and environmental resources. A struggle that benefits only the owner of the most powerful and efficient technology. BitterCoin takes up this discourse in a rhetorical way, It works as the most basic computer, increasing the time needed to produce Bitcoins almost an eternity.
