You can now generate your ANS address on Bittrex. But maybe wait for any official announce

No, but i would do my research on it, the same should you:

My antshares made visible few hours after my friends although we confirmed our privkey in same time..  
Now most important is for me if my ants are definitely lost or it is just visual bug?

@amintek15: i have the same problem like you. Invested on the first day of the ICO and cannot revieve my coisn in the wallet. I even wrote to a responsitive of antshares to give me a advice what to do but no answer. In the meanwhile the chinese investor are dumping their shitcoins on yunbi. I should have followed the advice of a friend not to invest in a chinese project because you didnt get treated fair. íts even disgusting that the blockchain isn´t in englisch also. This behaviour against all non chinese investors should be remarked for future projects

I guess it'll take a while before it can recover. shit happens.

For you guys not seeing your ANS and getting the 404 error on the block explorer, you are forgetting one very important step as listed here:

https://www.antshares.org/en-US/Blog/Details/42

1.        Visit the ICO page via https://www.antshares.org/ICO, click “query investment/get ANS”, enter your ANS address or Bitcoin address, click “verify” to enter the info. page.

2.        Enter your ANS private key and claim (left-bottom).

3.  Click “confirm” in the pop-up notice bar.

If you don't enter your private key on the Anstshares site and click the claim button and then the confirm button, your ANS won't be sent!

Hope this helps some people
