This one asking for donations as well?! LOL.
Thats like the 4th copycat "project" claiming to add privacy to XRB with no code shown ever, moderated thread, deleting comments when challenged as a scam, locking the thread, a lot of noob accounts singing praises to the dev and claiming that they have donated money. Overall red flags and warning signs.
So we have STONE, Paper, Manta and now this one. Could be the same guy behind all of them.
A scam alert thread has been opened here for STONE:
