Any investment decisions are always up to you. What we do is provide an easy way how to buy Chainlink once you've made your decision.
Having said that, there's a strong case for Chainlink. It provides a useful service that has applications beyond finance: a safe, decentralised, and reliable way to feed verified real-world data into blockchain.
This has plenty of real-world uses, ranging from online bets to something as simple as your utility bill. Moreover, Chainlink benefits from the success of other cryptos. If the blockchain technology is used more often, there is more demand for the service provided by Chainlink.
