Bitcoin is a digital currency that allows you to send and receive money over the internet. Unlike regular money, which is printed by central banks, bitcoin only exists digitally. It uses a special technology called blockchain, which is an open ledger where all transactions are stored. All of this happens with the help of encrypted keys that ensure only you can send your money.
How does bitcoin work?
Bitcoin operates through a network of computers called nodes. When someone wants to send bitcoin, a transaction is created. Here are the steps a bitcoin transaction goes through:
- Transaction creation: You decide how much bitcoin you want to send and enter the recipient's address.
- Verification: The transaction is sent to the network of computers, which checks that you have enough bitcoin and that you are not trying to use the same bitcoin twice.
- Mining and block: Once the transaction is verified, it is grouped with other transactions and becomes part of a block. People with special computers, called miners, compete to add this block to the chain approximately every ten minutes.
- Blockchain update: The block containing your transaction is added to the large blockchain, which is a digital history book of all transactions ever made.
- Transaction completion: Once the block is added, no one can change the transaction, and it is now complete and secured in the blockchain.
When did Bitcoin start?

However, its value can fluctuate significantly, so it's good to keep track of the current price ( ).
