I would like to voice a few thoughts.
For a long time, we have not been able to conveniently use Z-addresses due to the lack of a sufficient number of clients that support zaddr. But even now it is not convenient enough to do this. A couple of days ago, I tried to explain to a friend how to use zaddr and realized that doing this is terribly inconvenient.
Ok, To begin with, he needed to send coins from a mobile Jaxx to a mobile wallet that supports T-addresses and Z-addresses at the same time (the absolute majority of multi-currency mobile wallets do not have the ability to send to a Z - address-we cannot influence this within this forum).
The only wallet that supports both T-addresses and Z-addresses is ZecWallet. But my friend asked for a wallet with PIN or Face ID support (@adityapk00).
Nighthawk Wallet (@NighthawkApps) and Unstoppable Wallet (@Dadybayo) have such input protection, but do not support T-addresses.
In turn, all exchanges available in Russia do not support sending to Z-addresses.
All these factors create such a puzzle that my friend has no desire to use Z-addresses at all. I tried to persuade him, but no.
So… The fact that we have 700 thousand coins in a shielded field is a great miracle. (@zooko @joshs)
