With the August 1st deadline looming on us I would advise not to store your coins in a exchange, you should store your coins in a wallet that give you private keys, best would be a paper wallet http://toppayingsites.net/tutorials/how-to-use-paper-wallet-bitcoin/ I am following this tutorial, note this tutorial is not created by me, so any doubts ask out there. Choose your wallet really carefully it's scary times these days and if you don't have a private key, you could have a problem.
