Hello, I am very interested in the Tezos ICO, however I'm unable to post on the Slack

Is there any reason for investors to invest via bitcoin suisse, if the sale is uncapped and one month long. I'm interested in the product, and don't want to miss it. But will we be able to see how much is invested during this month, so investors are able to decide just how much they want to commit to the ICO?

Is the sale guaranteed to be carried out under these terms? How do we ask questions, if the slack is blocked to the public ?
