That's weird. The project seemed legitimate with its professional oracle solutions for smart contracts. I guess time will tell if LINK's success will last a lifetime or all the other way around. I've seen many cryptocurrencies and tokens come and go over time. Only those that are able to provide true usability, will gather the most mainstream adoption. With the recent popularity of "De-Fi", I wouldn't be surprised if LINK continues to reach new heights in terms of price. We may have to wait until the "hype" ends, in order to determine the true price/value of Chainlink.
If it works as intended, the Ethereum blockchain could benefit from it in many ways. Smart contract developers will be using LINK to interconnect the centralized and decentralized world. Oracles bring many benefits to smart contracts in the crypto/Blockchain space. Ultimately what matters here is mainstream adoption. If LINK has this, it'll be able to last for a very long time. ETH's low scalability greatly diminishes LINK's potential to transform dApps as we know them. But we'll get there sooner or later with the launch of ETH 2.0, making both ETH and LINK indispensable tokens in crypto land. Just my thoughts
