3. Screenshot doesn't really prove anything (as it stated before) - one can fake it pretty easily and it can be even automated.
The only way to prove ownership is to send small amount:
- someone send you request to approve he owns some address
- you reply with some random number (new number to every new requester) and some address to send to
- once your receive exactly this amount from address he claims to own you can be pretty sure this person is the real owner.
still labor intensive.
i don't know if it is possible to take snapshot and import private key.
better we have some easy to use solution.
and no more surplus. thanks
yes, it's labor intensive but you can't fake it.
easy to use solution = exchange "switch" coins automatically but we need them to enable depositsEDIT: ignore this ^^^ once everyone's coins is on exchange there will be no one to secure network and I'm not sure wouldn't this lead to some mess or not
