You probably won't find any reviews, given that their first post on Twitter is less than a week ago: https://x.com/Nexa_Cards

I can see them using the ticker $NEXA which is mainly used by this project (https://x.com/NexaMoney) but I cannot find the connection between the two.

But they must be connected with another project, because the amount of likes, retweets, and comments does not add up to the followers they have. So it's either that and they got retweeted by another main account of theirs, or they're just using bots.
