Before they're all focusing in the anonymity of bitcoin but they've found out that there's more private than bitcoin's transaction. And that's why they're all tracking those exchanges that still have it.
I wonder if some of the exchanges won't delist it overtime and will be firm supporting these privacy coins. Most of them are loved by its own community and has been established overtime.
I believe there will be exchanges that will still support these privacy coins.
Especially those that are not covered with strict regulations of their jurisdiction.
Remember, crypto exchanges are located all over the globe.
So it really depends on where they are licensed and located.
A lot are catered by these privacy coins, so there will always be a solid support on these coins.
