ChainLink is now an established project and star of Decentralized Finance (DeFi). Not very long ago, it made huge gains, brought early investors huge profits and is still rising. Sergey Nazarov is similar like Andre Cronje very famous and people trust him.
I see ChainLink as a TOP 5 project because it has developed a strategy to be important to any mayor DeFi project. Linking Chains will become more important where projects are doing cooperations and exchange of knowledge between projects is becoming a key factor for success.
Strategic partnership is already inevitable to attract a large user base.
Sergey Nazarov wrote an article about his vision few years ago and it's a really good one (but long to read):
