pirateat40 offered 7%/week while you are offering 7.21%/week compounded. Since you will use the new investors money to reimburse older investors (it would make no sense to do it another way and handle seggregated wallets if you need a continuous loan for your players), it cannot be distinguished from a Ponzi scheme until you either reimburse all the funds or fail to do so.
I get that you are not willing to publicly disclose your identity, but why not send some identification proofs to a few trusted, non-anonymous members of this community, with the explicit authorization to release them if you fail to reimburse funds without convincing explanation for a specified period of time (two weeks)? That should make everyone more comfortable trusting you with their money.
