If no BTC in the address is required, and the unique messages is just "BitCoinRhodium_" appended to a timestamp, how would you prevent a user from signing thousands of empty addresses?
We want to support newbies, and we believe they can be hardcore of our community and spread BitCoin Rhodium over the network. However, we have the control mechanism to control it.
So if I signed three-times? One from BTC address with BTC on and two with none? Will you kick me off?
