Sorry for the confusion, I'm marketing this on behalf of my client. It's $450,000 worth of WTT, I don't know if 21,000 is the Exact number, but he will be able to reassure with proof of the value etc. I believe he bought a lot a long time ago during the pre ICO.
and so its not your coin actualy ?
Why do not your clients sell it themselves, And how to secure your transactions with buyers its big money .
you need contact escrow first and make some detail in your offer maybe you can sold this token faster
