I wonder how you can tell if an address is on an exchange, for
example (don't worry mine's not). I'm just curious, I did not
think crypto-coins were that easy to track down, lol
To really prevent cheating you would have to require full proof
of identity, which neucoin actually asked me for OMG lol.
u dont need a proof of identity
u need a prove of controll of the private key of the address
such prove can be given by sign a message
the magi wallet have the sign and verify feature same as bitcoin
and this way u can prove address ownership
u wont be able do this with a exchange address (if u not the exchange operator himself)
and for sure u wont be able do this with a address u dont controll
