Anyone wgo can explain what is different keep beth on spot and beth staking?

Hello guys. I'm not good at english so just do my best for what is my problem.

The story is

1.I bought beth a while ago.

2.and I checked binance yester day and there have staking of beth.(flexible staking not a LP one.)

1. I thought if you holding beth on spot means you can get beth every day by eth2.0 staking reward.

So I don't know why there are new staking of beth,even you can get eth2.0 reward only holding Beth.

What is diffrent both of them? Did binance changed rule about holding beth on spot?
