Bitcoin was the first decentralized currency that was trustless in nature. Ethereum was the first decentralized smartcontract service that was trustless in nature.
ChainLINK is the first "bridge" between real life data and crypto that is decentralized in nature.
What does this mean?

ChainLINK can take real time datastreams like Sensor data/non-crypto financial data such as real time interest rates etc and combine it with smartcontracts.

What this does is create tremendous potential wealth and make businesses possible that weren't possible before ChainLINK existed.

Let's look at the examples of how ChainLINK could be used in real life with one thing that is already confirmed.

1.)A startup called Confido wants to make a payment and delivery system where they will use real time data from the delivery service's sensor system if a package actually arrived or not. When the sensor data confirm that the package is arrived a smart contract will automatically pay the vendor of that package automatically. This type of service would be impossible with ChainLINK if you'd wanted to make it trustless without 3rd party meddling.

2.)Trustless Gambling
Racehorses gets sensors in them whichever reaches the finish line first gets their data send to ChainLINK which then through smartcontract pays out everyone that betted on that horse. Online gambling where the roulette has sensors in every landing place and automatically pays out to whomever betted on that automatically through ChainLINK.

3.)Trustless Insurance,Trustless Warranty
When you have a car it could automatically send it's realtime data like speed,GPS position and miles driven to ChainLINK. And it could in real time change your insurance terms based upon your driving behavior and if you crash your car pays out (or not) automatically based on these sensor data without needing a third party.

Same for Warranties. If the sensor data shows the warranty should apply it could automatically pay the party or if it is voided it automatically voids the smartcontract.

4.)Connecting all currencies
ChainLINK can actually be used to link different currencies such as dollar,euro,yen with all different cryptocurrencies and each other. Because you can input real data into it you could make it so that banks could "lock in" things like "Bank A coin=$5" and based upon how much other coins are worth in real time feeded to ChainLINK would make it possible to buy "Bank A coin" with ALL different cryptocurrencies even though they only accept dollars.

5.)AND LASTLY, New bank shattering application
You know when you pay for something and you don't want to use your creditcard because of fees? So you go and do a wire transfer straight from your bank to another one.

But then you usually have to wait a couple of days or even a fucking week if it's international and you are unlucky.

Well. ChainLINK is the solution to that. A bank (or third party application) could just feed the information from Bank A that you made a wire transfer to Bank B. And then through ChainLINK combining that data with a smart contract Person that has Bank B account gets paid that money immediately and so the vendor/friend/whatever that uses Bank B knows that he got paid even though he hasn't received the money yet and thus can give the guy from Bank A his goods/whatever immediately. Thus cutting out Creditcards/Wire transaction time and everything WITHOUT having to use cryptocurrency per-se as the end user.

LINK IS A GAME CHANGER.

Sure you can say "There is no guarantee it will be adopted" or "Why won't every of those businesses not just program their own solution".

But I could say the same thing about ETH "What if smartcontracts won't get adopted?" "Can't companies not just program their own smartcontract services?

The answer is NO. Because the value is added due to it being DECENTRALIZED. There is no third party that can meddle with the transaction. It's all real time based on sensor or other outside information which gives security to the users.

I hope some of you understand the potential of LINK some more right now.
