Sorry I do not accept you jumping from alleging the OP is an imposter to the whole arbiter drama. Who is the arbiter?
Can you provide the name of the arbiter and also state what your relationship on a personal and business level has been with this arbiter?
Can you also explain what it was that made you choose this arbiter over others? Also, why did you appoint an external 3rd party (arbiter) unilaterally without even discussing it as an option with the OP?
It is mandatory to do a full KYC regardless the currency. At least in Italy but, as far as I can see, even major off shore exchanges such as Binance. are requiring a full KYC now.
We are positive about this because, not only our lawyers told us wht to do but, during a routine inspection by the financial authorities, they confirmed the procedures.
I wish I could send out crypto without KYC but, I cant't.
Also, there is another problem. I'm not positive the OP, even though he had access to the account, is the real owner. How would you solve this problem??
This is why a qualified third party such an arbiter, could explain to the OP what he/she has to do (for us is a SHE).
Thank you
Sorry, but these are privileged information available to the OP only which is also allow to change the arbiter.
