Utility is not driving the price, it is pure speculation. So get out while you can, it's gonna dump hard.

Chainlink isn't decentralized either, which is kind of laughable. They didn't even move to their own blockchain yet, which could be a disaster if they want to rely on nodes running their oracles. Ethereum uses a centralized data protocol called Infura to process data between the ETH main chain, and it's tokens. Infura is a single point of failure, which could shut down the whole ETH network over night, making these "oracles" completely useless, as they cannot function without Infura in place.

Blocknet is making their own data protocol, which doesn't have this vulnerbility, which can process ETH based data in a decentralized way, which would benefit ETH a LOT.LINK is a hyped up project with a lot of "muh partnerships", to pump the price up. Tech wise, it's really not anything special.
