Btw does anyone here know what type of wallet I should use to hold your tokens?
AZ is an erc20 token, so MetaMask is a great choice. I personally use it and never had any problems. It's very simple and convenient.
But if you want more security, consider buying a hardware wallet.
Actually hardware wallets dont support every erc-20 token, only a number of listed ones. You still need to use MyEtherWallet, for fresh ICO tokens.
