Hi,
May I know, why you put abucoins & BTCC at Tier 2 ?
For Kraken & Bitstamp, with their current support quality, I don't think that they still deserve for Tier 1

You can read on this Kraken official thread :
https://bitcointalk.org/index.php?topic=290799.6440There is a lot of problems unsolved, including mine..
For Bitstamp, u can find a lot of threads that list disappointed customers with their unsolved problems..
And, in case of my account verification, I have sent all of the required documents more than 1 month ago, then they just email me asking again the document that I have sent more than a month ago.. I think they will need another months to check the documents that I have sent to them (in case they don't lost it again)..
And their Cust. Support needs weeks just for replying with something not helpful at all, & just copy-paste from their standard reply.. Sometimes they even just replying my email with different topic than I have sent (so I don't think that they even read my email)..
I think I should reconsider to trust them with my fund & assets.. considering that they even can not keep the documents that I have sent to them..
For this moment, It's hardly exist any "big" exchange with a descent service (especially support) quality.. Please let me know if it there
