Oh so so far what has made Chainlink's price go up is because of the cooperation with Paxos, it's no wonder it has risen so fast and this has increased very drastically.
As far as I know, Paxos is a coin that is on the erc20 blockchain and has a stable price of 1:1 with USD.
And PAXOS is also heavily traded throughout the market and this allows Chainlink to adopt it for the security that Paxos has for every transaction.
