Bitter Coin is an old calculating machine hacked to be used as a data extraction system, validating the bitcoin pending transactions in the Blockchain. Bitcoin was originally conceived as a decentralized electronic system for capital transactions. Each node (user) has the same opportunities to receive a reward when validating a transaction. In recent years, this system has been unleashed in a competitive struggle in which computer power is the most important variable to earn Bitcoins. This involves the use of large equipment, computer farms that consume physical and environmental resources. BitterCoin takes up this speech in a rhetorical way; it works like the most basic computer, increasing the time needed to produce Bitcoins to almost an eternity.
