What is the minimal pay to invest? How can I exchange ıngot tokens for fiat or other cryptocurrencies?
Depends on the Ico stage.
For Pre Ico, Minimal payment is 2.000 and for the normal ico stages 100 is the minimal payment amount. Of course the equivalent in ETH will be set before the ICO.
Not sure what you mean with the "ingot Tokens"? Could you describe more detailed what you mean? Thanks!
