I just discovered SNAX thanks to this post made by 
Their website is pretty well done and you get easily what they want to do.
Basically, as you can see on the picture, they want to reward people for their social activity (on Twitter, Facebook, Instagram etc) without leaving the social platform.
At the moment, only Twitter is supported.
To create a wallet and claim your SNAX you just need to download a Google Chrome extension called Snax.One.
It is working locally so it won't store any of your datas related to your account.
You will get an airdrop of 50 SNAX just by signing in and you could have some more if you write a post about it on steemit.
The reward will be function of your followers.
For example with 500 followers you will get an additionnal 832 SNAX.
Regarding the potential value of the token it should be very low at the beginning giving that there will be 100B tokens issued just for the 1st stage.
Anyway it is always pleasant to see some newborn projects like SNAX that will help crypto adoption.
