Best and safe to invest
Binance Coin (BNB)
Market cap: Over $64 billion
The Binance Coin is a form of cryptocurrency that you can use to trade and pay fees on Binance, one of the largest crypto exchanges in the world.
Since its launch in 2017, Binance Coin has expanded past merely facilitating trades on Binance’s exchange platform. Now, it can be used for trading, payment processing or even booking travel arrangements. It can also be traded or exchanged for other forms of cryptocurrency, such as Ethereum or Bitcoin.
Its price in 2017 was just $0.10; by Sept. 30 2021, it had risen to over $382, a gain of more than 382,000%.
So the bullish trend is on and is safe for investment
While BNB generally follows the BTC trend (sometimes with a short delay) in its price movement, it's worth noting that this coin is also valuable as a source of Gas for the Binance Smart Chain.
If you're trading on Binance there are several advantages to holding BNB like fee discounts an option to participate in Binance Launchpad (i.e. free tokens for staking).
But putside of Binance and the BSC ecosystem I'd say investing in BNB is not much better than investing in Bitcoin.
