What is the easiest way to convert my bitcoins to USD and then send to my overseas account (in Singapore bank account). Alternatively, any easy way to send the same to international credit card (VISA/Mastercard)? Please note that amounts are small, so direct wire transfers will not be feasible.
Can't you just convert them to $ on mt.gox and then withdraw them to your account? mt.gox does have a Honk Kong bank account, so assuming they do it form there there shouldn't be any fees.
You should ask them if they would do it from their HK account instead of their US account.
