Ian Miers’ Zcon0 presentation on the importance of financial privacy, and how technology can be used to achieve it, is now available as a professionally edited video. You can watch it on YouTube.
There is no privacy with crypto. And I don’t see how there can be. People want to spend it but then don’t buy anything that has to be delivered to your home address.
Z addresses provide privacy do they not? Even if you have to send to t addresses to buy something you just need to change amounts in vs. out and there is still reasonable privacy, more than any other coin.
