BNB is the internal token of the Binance exchange. Despite the fact that now this exchange is among the three best cryptocurrency exchanges, and its token is highly valued, it is still an exchange and its work is subject to greater risk than the ethereum network. Regulators may impose various requirements on the exchange, for example, to identify all customers, regardless of the transaction amount, and to do this with each transaction. If such requirements are met, the popularity of any exchange will plummet. In addition, any cryptocurrency exchange is at risk of being hacked, and this also affects its popularity and the demand for its token. Therefore, I choose the leader of altcoins ethereum in this comparison.
