where is best place to store protex?
i need have in wallet or i can have in offical website?
Its an ERC20 Token you can store it in any ERC20 compatible wallet such as myetherwallet. I personally would suggest myetherwallet, as it is the best and most convenient one to use. As for storing coins/tokens on a website, I would never do that, always make sure that you control the private key by yourself and dont store your coins where somebody else got control over them, such as on an exchange.
Dear Protex team, the communication from your side seems very thin, so I ask again: can you please provide me with the slack invite link, I am waiting for it?!
