Of all these options will be best for me to take part in the Qtum crowdsale on the official website. For the Asian market, Asian exchanges are good, but for many people it would be convenient to use such as the exchanges like Bittrex or Poloniex. I hope that later Qtum will be traded on them too.
I am sure if you have taken a little time to look into the few responses before your comment, you will understand the reason why those exchanges you are making references to are not listed. I am sure that if they have their way, ( I mean the management of Qtum) they would have gotten listed on those platforms. Also we should also not be weary of not patronising other exchange sites so that they can grow as well.
