Even the ones i'm with are not answering when I try to change the address on my account (which i need to do before I cash out any coin ..for tax purposes).
Which exchange do you use? I assume you live in the US, right? as you have to pay taxes for withdrawal cash out of the exchange.
are you referring to coinbase or gdax? have you ever tried Kraken?
Do you mind if I ask where do you live? which city? as maybe you can visit an exchange office to do over the counter transaction to withdraw fiat currency.
Or else, you can try to check the localbitcoins website or offer personal trade to someone in this forum who lives in the same city as you, but be careful to do this, make sure to use escrow or meet in person.
