Careful with Chainlink, although a promising project, I don't think it's current price is justified compared to use case. A lot of people will hate on me for saying this out loud, but it's been gaining pretty heavily lately, and at some point it's gonna come crashing down on you, guaranteed. There is no guarantee that it's gonna continue gaining in value like it has previously.

Blocknet, a project similar to Chainlink, yet way way more decentralized in it's structure is a better play in my opinion. Not only do they work on their own decentralized oracle network (in beta, so you can try it out on your own) but they where also the first project to launch a truly decentralized exchange: https://blockdx.com/

Read more about their XRouter/XBridge, and their oracle network here: https://blocknet.co/xrouter-missing-link-between-all-blockchains/

Blocknet is an old project from 2014, saw a price jump of more than 300% as of lately, and seems to continue it's trend upwards, why?
Because a LOT of people want to secure a Blocknet Service node (5000 coins required). As a node operator you'll be able to profit from the oracle network services + block rewards + DEX fees.

In a couple of years you could easily make a living off a node, I'm sure.

Good luck, and remember to do your own research man
