You forgot about Cardano, it is the second biggest coin that could be stake after ChainLink, but approx. year reward is much higher than on ChainLink. You get around 3.5% interest per annum, which is much better than in any bank. 
This is a nice list also. Has anyone seen the mantradao project? I think everywhere I look on social media even on twitter, this project really on news. Ive searched a bit and they are offering staking with APR of 88% one of the biggest Ive seen so far. They are listed on bithumb and currently have staking tokens there. I didnt get the news about that but If only I had I will joined the presale cause its very cheap compared to now.
