The address that I'm using to mine is my address from poloniex, what do I need to do to show you that I'm the owner of this address? I don't want to use any other address.
For your own good, switch over to bittrex if you 'must' mine to an exchange.
Poloniex disables wallets without warning, support is non-existent, collapses on weekends during pump hours, delays large deposits for weeks, must one go on?
Long term if you're serious, https://github.com/vaklinov/zcash-swing-wallet-ui is worth while if you don't enjoy executing one line of commands after another.
I agree with Anon. Been waiting a month for Poloniex with no response. I highly recommend never mine to an exchange wallet. I never had good luck doing that.
I have freewallet app on my phone I mine to that. I get an email every time I get a new deposit. Granet there is like an $11 difference from the flypool to freewallet app... (wallet shows the lesser difference)
