For 2 what if you were able to have initiate a buy/sell order via a exchange API that services both coins?
The problem is verifying on both cryptocurrencies that the exchange took place without having to download the whole blockchain of both cryptocurrencies.
Looks good. I wonder how easy it would be to implement though?
Would be great if the client could have this design from the start.
I hope we can have a wallet that opens very simply like Bitcoin wallets do, and not the NXT way of having a web-browser wallet.
Creating a custom design takes a lot of time if you want to make it work properly with java swing.
At this point I prefer developing the core and features instead of developing the GUI.
About the GUI, I think you can let other people do.
