Why does Bitcoin use electricity?
Bitcoin is a digital currency, and it works through "mining." Mining means that computers solve difficult mathematical problems to verify Bitcoin transactions and secure them on the blockchain.
These computers are very powerful and work day and night, which is why they consume a lot of electricity.
More miners = more computers = more electricity.
This electricity usage is necessary to ensure that:
Bitcoin remains secure
No one person can control it
The system is transparent and honest
