bnb falling at this time when many are blocking sales indicates that it is not a reliable currency.

The dollar was once the pillar of the global economy, but behind the scenes in the digital financial world, another currency is leading the way: Binance Coin (BNB). Haven't noticed yet? Let me explain:
BNB is the currency of exchange in the largest digital financial market on the planet.
With billions of dollars traded daily on Binance, BNB is not just a coin, but the foundation of an entire ecosystem.
Real vs. digital economy.
While governments print money without limits, the BNB follows a deflationary model: the more it is used, the scarcer it becomes. And what is scarce becomes valuable.
