In my wallet version 0.70.0 the Encryption option is inactive. Let's wait for comments from other users.
Sadly, that's all you can get from this project.
The dev team is non-existent in the public and when they do put out news like that interview they just did, they shoot themselves in the foot by saying things like there is no official road map and they have no timelines on anything.
BTC up, HUSH down,
BTC down, HUSH stable,
BTC stable, HUSH down,
rinse, repeat
This project is sinking faster than SIGT and LBRY did.
Get a positive public presence before it's too late, people are paying attention, you just have to give them something instead of puttering along without any concern for your community or your reputation.
I also decided to dump now, the markets are running away. The thing is, I am under the impression that the team (and others involved) wants to steer HUSH into the decentralised market space where attention is placed on making it more valuable in the BarterDEX.
Those punting HUSH, some say that you must exchange your HUSH on the DEX to Zcash and then move it on a centralised exchange. This idea is already out there.
I am not holding the unknown.
