~ Binance will also support this coin for staking reward.
Where have you read that? Link please.
Binance & Zil staking will be a great solution, but I doubt that this is something we will see happening
As of now, we didn't hear any news about Binance is going to support the Zil coin for staking. As of now, Zilliqa team didn't release their live version of staking platform and it might take some time to release the live version. Once they start releasing then we might expect soon Binance will announce about the Zil staking.
