Your WP is so huge, by far the largest I've seen! That's so cool

Total supply is in millions, right? Not 703 b? Am I confusing it?

The total supply is 703,125,000 tokens.

Couldn't find the minimum investment?? Is it still 10k dollars?

The only thing you need to particupate in your ICO is ERC wallet and money?

Yes, you totally can. There are no restrictions put on Australian nationals.

You are almost right. There is one thing you need to do: you have to go through KYC procedure.
To participate in the Token Sale, you need to sign up and log in the account on Zichain website, go through the KYC procedure, and pay for Zichain tokens. We accept Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC).

And 450 m for main sale?

So your tokens will be tradable on excahnges?
