When will the registers be open again?
The plan is to run the affiliate campaign again around the June 19-21 timeframe.
We will likely get less than a day out of it before we have to shut it down again, so we're going to try to get it as close to the ICO date as possible.
Specifications for this coin? Total amount of coins, etc?
See OP. The specs are listed there in the infographic. And there's more detail presented in the white paper if needed.
How do you send the SilverCoin NXT asset from a NXT wallet to the SilverCoin wallet on an exchange?
If you have silvercoin in your downloaded NXT wallet, you can just send it directly to the SilverCoin wallet on the exchange. (which is a NXT wallet underneath)
the only thing is that you will need 1 NXT in your wallet to send it. That will not be the case when Ardor comes online so it's a short term thing.
