This is one of the main reasons I haven't used bitcoin (crypto currencies). It's practically impossible to get a straight answer on what it might cost to cash out.
Well your question and the replies have nothing to do with "bitcoin" itself. You are asking about the details of some centralized service and there was already a straight answer (first comment). This is not something we can tell you, only that centralized service can do that because THEY are setting the fees which again have nothing to do with bitcoin. They can simply decide to charge you $1900 to let you cash out $2000 or charge only $0.01.
