cryptocurrency

Bitcoin is a cryptocurrency and worldwide payment system called the first decentralized digital currency. Research produced in 2017 suggested that only about 150 to 200 bitcoins were actually being mined each day. At price levels similar to those seen immediately before the start of bitcoin mining, bitcoin transactions would have cost 10 million dollars per day. At high prices, low electricity costs and declining costs make mining profitable at rates higher than $20,000 per coin.
