I wonder how I am supposed to sell bitcoins on an exchange. I have been considering several and have gone through the KYC/AML process for three exchanges. The problem is once I sell my coins they might ask me to prove where I got them from. Keep in mind I am not intending to withdraw the FIAT, I just want to sell high and rebuy lower, and withdraw the coins.
The problem with proving the source of my coins is, how the hell do I do it? I bought them on MtGox and they can't ask MtGox for verification. Even if they did, the coins have gone through several addresses over the years. I can't even trace it back to the MtGox purchase since they went through other exchanges (and got mixed).
So what is one supposed to do here?
I never experience that up to the present since I've sold bitcoin many times before. why don't you try to do in the other exchange exchange so you may not encounter that kind which is something fishy going on. Try Poloniex or bittrex.com
This is the something I want to said you experience is very strange. Have used poloniex to transfer before and I was never ask to prove how I generate my bitcoin or other crypto currencies! I think try others exchangers again outside the one you done before and I think you will successfully convert you coins.
