Why This Matters
Staking is a great way to generate passive income and Binance Coin (BNB) is the native coin of the best blockchain (BSC) for DeFi.
However, staking BNB has been particularly difficult for American investors (who can only use Binance.US and not Binance.com) --- until now.
Simplicity: Staking Option Displayed Prominently

It is difficult for anyone to miss the new staking tab, situated right beside the big Buy Crypto button at the top of the home screen.
Super Solid APY

As of today, Coinloan offers 5.2% APY on BNB deposits as of today -- and 5.2% is a very good rate. However, Binance.US' 6.40% APY is ~20% higher, rewards are paid weekly (every Friday) instead of every month, and unlike Coinloan, Binance.US provides a fiat-to-BNB ramp.
Of course, those who prefer to stake directly can currently get a slightly higher APY by doing things "the old-fashioned way" (delegating BNB from Binance Wallet to individual validators), those APY's fluctuate and the process isn't as simple and potentially less secure.
Stake with Binance.US or Go Solo?
I've personally decided to do both: I'll continue to stake BNB directly from my hardware wallet and I've deposited some BNB into Binance.US' staking platform. It's an easy decision for me because I already went through the trouble of learning how to manually stake BNB via cold wallets and currently have BNBs delegated and earning rewards now.
If I were a total newcomer, I'd probably just embrace the simplicity of staking with the exchange now that that's an option.
Updates to Come
I started staking via Binance.US just 24 hours ago, so I'll have to wait before I can accurately assess its quality. However, in my opinion, adding staking to Binance.US should prove to be very beneficial for investors and BNB alike.
