$BNB Binance currency was originally based on the Ethereum blockchain and followed the ERC 20 standard, but it has subsequently become the Binance chain's native token. It was launched in July 2017 as part of an initial coin offering (ICO) with a cap of 200 million BNB tokens.
Through the ICO process, it provided 10%, or 20 million BNB tokens, to angel investors, 40%, or 80 million, to the founding team, and the remaining 50%, or 100 million, to the various participants.
