I'd expect privacy networks to be taken away from centralised exchanges to outcast them. They'll be used but won't have activity because ppl won't be able to get fiat from centralised exchanges if they've originated from privacy networks. When ppl realise they won't have private info in centralised exchanges how many are going to use privacy networks?
In near time Monero could increase trades but we don't know if ppl will feel safe using it if they're sending exchanged crypto to centralised exchanges when they want fiat.
Privacy network simply gives better edge compared to Bitcoin network. I don't consider the Monero a network that has much traction because people are silent about it. The reason for the silence is not because people don't care but because they have little or no information about transactions that goes on in there.
In no distant time, I believe that privacy netowrks like monero will gain traction and still leave its users safe and secure as the transactions can not be mirrored like it is through the Bitcoin network.
This will also make projects migrate to privacy chains and another wave of boom will emerge for them.
