Who would use DeepSend for $6 or $60 or even $600. Well, it must be limited according to the monocolor because the nodes must have twice of the DeepSend tx amount. In that case, if we consider real scenerio, at current price, I doubt anyone would use DeepSend.
Most of the people who are concerned about such privacy, would do a tx of a few thousands worth coin at least. But that's not possible, right? Even if the system allow higher amount, how much node will we have and how much decentralized can we call DeepSend. I don't know. Please DEV team share some more details on it.
Why would anyone do DeepSend 30 times while they can be private with one tx in Monero or even with BTC mixing?
Next version: The maximum limit of deepsend is 1000 onions, and the current price is $60. Depends on the price of onion, as the price of onion fluctuates.
