You should not delete evidence of receiving funds from any services, as this may become a problem for confirming the source of funds.
That's not up to you to decide. When I use Bitcoin in a shop, they don't ask me where I got it. Exchanges in the Seychelles shouldn't ask for my personal administration either.
Any response to this?
Okay, hypothetical: let's say you've blocked my funds, and I tell you I got it from the
Currency Exchange board. A simple, honest p2p trade. Is that enough for you to return my funds?
I take it you don't want to answer it, which is fine, but I'll draw my own conclusion.
