Bitcoin is a digital asset and a payment system invented by Satoshi Nakamoto. Transactions are verified by network nodes through cryptography and recorded in a public dispersed ledger called a blockchain.
Bitcoin is unique in that there are a finite number of them: 21 million.
Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.
As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.
When looking for Bitcoin Promo Codes, be aware that there is no guarantee that the code you find will actually work or give you the discount you expect. Be sure to research the code thoroughly before using it and only use codes from trusted sources. Additionally, be aware of any fees associated with the code and any terms and conditions associated with its use.
Bitcoin can be used to pay online and in physical stores just like any other form of money. Bitcoins can also be exchanged in physical form such as the Casascius coins, but paying with a mobile phone usually remains more convenient.
Bitcoin balances are kept using public and private “keys,” which are long strings of numbers and letters linked through the mathematical encryption algorithm that was used to create them. The public key (comparable to a bank account number) serves as the address which is published to the world and to which others may send bitcoins.
The private key (comparable to an ATM PIN) is meant to be a guarded secret, and only used to authorize Bitcoin transmissions.
There are various ways to get a promo code for Bitcoin. One way is to go onto websites that specialize in Bitcoin coupons and offers, such as SpendBitcoins or Bitcoin Free on Reddit. These websites offer codes for various merchants that accept Bitcoin, such as Dell, Microsoft, and Overstock.
Another way is to find codes offered directly by the merchants themselves on their websites or social media pages. For example, Gyft offers codes for discounts on gift cards which can then be used to spend Bitcoin at retailers such as Target, Amazon, Starbucks, and CVS.
