I mean what do you mean by "worth looking into" though?  Like obviously everyone is going to say this is the best privacy/fungibility/overall cryptocurrency project, but if you are looking at smart contract platforms, storage solutions, etc. I like to look at it in 3 ways:

1) Does it do something that previous coins simply aren't doing

2) Does it actually use the block chain to circumvent third parties/governement, or are just looking to use the blockchain for the sake of saying their project is "on the blockchain" to make it sound sexy.

3) Is the community actively engaged and actively developing

Example that I've seen recently where it seemed like a good idea to look into the project but I stepped back from it was looking into Cardano.  There are aparently a lot of really smart people working on it, and are some actual things they are doing that are a little differently than others, even though I didn't believe it would work, I was intrigued about this new PoS system called ouroboros but didn't get that far into looking into it....

Primarily because I had remember seeing 1) They treat Charles Hoskinson as this genius/visionary/CEO type guy where if he goes down in some way, then the whole project would probably fall apart, and 2) I remember reading something along the lines of Hoskinson saying that he would be wanting to work with governments to get Cardano "approved"... idk I honestly don't really remember, but it was something that didn't sound like Cardano was planning to being very decentralized... the primary thing a blockchain is supposed to do.

TL;DR DYOR
