What happens when you don't have any coins left? For example, what if someone deposits 100 BTC (which is extremely unlikely at the moment, but say if) and expects to earn 1 BTC every month? Can you handle it financially? As far as I'm concerned, you have not disclosed the amount of personal stash you have. If you don't want to do that, which is very reasonable for a service like this, then perhaps limiting the amount earned is a wise choice.

So basically what you're trying to do is take loans from every depositor.

We mentioned in the ANN thread that we are expecting to pay up to 6 BTC for this campaign, but we can handle it even if it goes beyond that. Keep in mind that a portion of the multi-sig balance would be our own reserve, so the 'real' amount of rewards paid out is always lower than the amount stated publicly.

We did not disclose the amount in the 'personal stash' not because we don't want to, but because as said from the beginning we intend to use it to permanently increase the multi-sig balance and the Anonymity Set by blending it in with other users deposits. If we were to disclose any of the wallets we intend to use for depositing we would incur extra costs to obfuscate the trail again before doing it and that would be pointless, we'd much rather spend that on Anonymity Mining rewards. You will notice that as soon as deposits start to happen more frequently the balance will drastically increase and it will never come back to the current levels.

'Taking loans' is one way to look at it, but it's not entirely accurate since we do not touch customer deposits, nor do we care about how long they are kept inside Whirlwind. We are only interested in 'artificially' boosting usage for a while until the Anonymity Set is big enough to accomodate large deposits/withdrawals without it being a privacy concern.

From what I read, it is no clear to what extent a seizure or the bankruptcy of the service providers would impact the stakers. A 12% APR is a very promising profitability for a money that is otherwise frozen, but it has nothing to do compared to the loss of the 100% of the capital, if these problems happened.

If I'm wrong and there is no risk associated because Bitcoins are retrievable at any moment no matter what, then I will have to think it twice.

There is risk since it's a centralized service. Your BTC is retrievable at any moment only as long as Whirlwind is running, so you need to trust us if you want to participate in the campaign or simply use it for privacy.
