EXW Wallet is ponzi scheme offering 0.31% daily return (among other things). Another thing that is interesting is that registration is not possible without referral link, and OP of that thread shared that too. So it seems to me that he is just spreading this scam. But i think that is important for others to see that this is ponzi, before someone invests in this.
