Your welcome but you have to understand that I wrote this 1 year ago when I was first learning. Bitmex is a good exchange but it is bad for new and amateur traders. Also poloniex used to be a lot better back then, I don't not use polo anymore either because there TOS has changed and they are not good in customer support just like you are saying.
RE: WTF! Due to local laws, Bitmex is unable to service your country(US)!
