#HODLTradingStratergy BNB, originally known as Binance Coin, is the native cryptocurrency of the BNB Chain ecosystem, formerly known as Binance Chain. It was initially launched as an ERC-20 token on the Ethereum blockchain in July 2017, but later migrated to the BNB Chain. BNB is used for various purposes, including paying transaction fees on the BNB Chain, participating in the network's consensus mechanism, and as a utility token offering discounts on trading fees on the Binance centralized exchange. Bitcoin works through the collaboration of computers, each of which acts as a node in the peer-to-peer bitcoin network. Each node maintains an independent copy of a public distributed ledger of transactions, called a blockchain, without central oversight. Transactions are validated through the use of cryptography, preventing one person from spending another person's bitcoin, as long as the owner of the bitcoin keeps certain sensitive data secret.[7]: ch. 5 

Consensus between nodes about the content of the blockchain is achieved using a computationally intensive process based on proof of work, called mining, which is performed by purpose-built computers.[7]: ch. 12  Mining consumes large quantities of electricity and has been criticized for its environmental impact.[9]
