If you want to stake for BNB, it's a good idea to use the Binance platform. It will be more secure for your assets than using other platforms. The advantage of staking on the Binance platform is that you will get a share if they release an airdrop, or as a BNB holder. The risk of staking is that you lose the opportunity if the coin price is rising. You cannot sell them if the coins are still staked. Another risk is that you can't sell it if the coin price really drops.
You can stake if you are a long-term holder. It was very profitable because the number of coins had increased.
