A non-disclosure agreement, itself is actually unenforceable without agreement and consideration by both parties. Since the issue is related to the redemption of physical currencies, there would be no NDA applicable - regardless of size of funds. This has borne itself out at the Supreme Court level.
However, the redeeming entity, can and will issue a release letter that outlines the terms of the 'deal' and legally requires endorsement of disclosing parties - including the binding non-disclosure of terms. There are several interested parties that need this in order to allow the redemption of your funds to transact.
I say these things, not to split hairs - but to point out errors in group think.
Shame on all of you sheeple for letting a legally required document that protects your right to access funds from redemption - that will be required by not just law (IRS, SEC Audits, Treasury guarantee that these currencies are submitted to them free and clear without illegal acquisition etc.) - that you actually think you can hold up a process that allows for voluntary redemption. You actually are no different than the cartels and cabals - and are centered on both greed and pride. Is your understanding of life, and the gift and blessing to receive and help in the elevation of humanity so tainted that you immediately undermine the core tenets of the event with putting conditions on it?
Imagine if God, the Creator put conditions on His love for humanity... then you who entrench on this thinking would certainly never be in a position to be baptized in this endeavor.
