I have the hush address and the private key, but I deleted the wallet because it did not synchronize. Just with this how can I do to send hush to cryptopia?
You can simply go here:
https://wallet.myhush.org/Click on settings button (shown right next to "Hush Wallet" text), and select "Paste private key". Then simply put your private key there and have your wallet unlocked. You can then view your balance or send hush through it.
Exciting stages coming for hush soon.
