Thanks .
just an FYI ZEC is sold in every exchange without any issue maybe the exchange has certain rules you must abide by and i agree if the exchange says mst be unsheilded then thats what you must do but between 2 private parties why cant you make a shielded TX ., by the way most exchanges i have seen in Aus sell monero if the exchange doesnt allow shielded it will stipulate , and its only an option if the wallet provider decided to implement it. Some countries require this privacy from their tyranical goverments, oThat is why the standard transaction is non zk-snarks you have to decide wether you want to make this transaction or not , z-cash has been approved by some government entity which is basically the same it has shielded and non shielded unlike monero where it is the standard and you must transact privately
