@alan8325 If they screwed up, sure. Monero is certainly easier to use privately than on-chain Bitcoin, as reasonable privacy happens by default without any extra effort.
@alan8325 Complexity probably. More work than Monero. Also, the typical transaction size (in terms of BTC) might be high enough that they're not sure that they'd be able to reliably keep sufficient channel capacity.
@pete Providing incoming liquidity to what you suspect *might* be a DNM node would be a spicy fee source.
