The fact that there are over 17 thousand DAI, still available to cover the damages of any whirlwind user, pinpoints how upright mixer that was.
Even ChipMixer didn't do that, and I'm pretty confident that they've had the financial capacity to manage it.
It's good to hear that they're back but does a blackout that lasted for the amount of time that it did
really mean that whirlwind is "upright"?
Chipmixer didn't do that because they got seized by authorities.
Though I suspect they will be; I think that we should not forget the facts conversed during the panic. We should also not forget core foundations of Bitcoin - decentralization and trustlessness. If WW ceases to operate at the unannounced will of the operators, what does that say about reliability of service? What if something happens to the operators? This is not decentralized, nor is it trust-less.
I would strongly advise against storing your coins in whirlwind notes.
