You can prove that it is your Token, but not that you have 100% no control over it.
Yes, so to give me the stake the regular way prior to the tokens becoming worthless, then if I was shady and lying about being locked out, I could then sell the token. But if we wait until the token is worthless and I can not sell it, then it doesn't matter if I have control over it or not. Just that it is my token.
And I still have control over this account. And this is the account that requested the token.
This is a trustless decision. No one is needs to trust me that I am telling the truth because when I receive my stake the regular way, there is no way for be to go back and claim the token because it will be invalid. So it is impossible for me to get two stakes, even if i was a scammer.
Yes, you will have to wait until the stake is no more claimable and that the token is dead and that you can proof ownership of it.
And despite all the fuds, a deadline is important because we do not want people to lay claim that they never got their stakes because they were "not aware". This only opens up scam opportunities.
Scenario of a scam:
Sieze control of an account. Lie low and wait for anyone to report lost of control of this account. 6 months later, account still remain dormant. Scammer now surfaces out and says that he has a stake to claim and that he was "not aware" there was an exercise to claim stakes.
Of course there is still another possibility that the scammer claims right from day 1. But that would raise alarm and can cause them the stake as it will allow us to take counter measure.
In any case, there were only a few who wanted indefinite time to claim. So, there is no issue, i.e., there will be a deadline.
Sorry for proponents of no deadline. In fulfilling the greater objectives of an initiative, like I said, not everyone will be pleased. And we will have to work on that premise.
