I watched as Monero was gradually dropped from a lot of the major exchanges over time with no real reason being provided. Same with zcash. My conspiracy theory is that there is a coordinated effort to make truly anonymous coins unusable.
Non-cash anonymous financial transactions have been no-no for a long while, in particular under AML/KYC.
Over a certain amount, even cash transactions get wrapped in KYC/AML papertrail for law enforcement facilitation.
Monero is only available on the exchanges operating on the fringes of the banking network, or which don’t connect to banks at all.
