Cool! I learned about that noise.cash last month and the payouts are indeed legit. I linked it to my local mobile wallet which fortunately accepts BCH and was getting transfers for every $0.01 I got which at that time drove me crazy (I forgot to set my minimum withdrawal at that time).
Loved it! Although I don't think it was for me since I really suck at engaging especially towards strangers to which I think at the moment is noise.cash is mostly for.
Will follow you later once I am on mobile :)
