The smart thing to is check out the social media presence and the github activity.

But ONLY rate the social media content that has a direct input to the viewer from the developing team.

Less importantly, but still a factor, (remember Bitconnect?) - check to see of it has a big or growing community. Tron has this, but might have Frankenstein coding.

So, on this basis, you have to rate Cardano very highly.

Neo apparently very active on github, etc... (I'm not intersted in Neo, but you have to respect proof of technical development)

Code reviews? Well, Grin got a great code review recently, so I'm looking into it.

Good luck to you all
