Video Walkthrough to Use the IICO Platform


What is an Interactive Coin Offering or IICO?

The IICO is a token sale mechanism proposed by Jason Teutsch, Vitalik Buterin, and Christopher Brown, in which buyers can specify minimum and maximum prices for their participation.Its price discovery mechanism attempts to maximize market information for buyers so as to converge to a true market price. It incentivizes spectators to assist the smart contracts with complex operations.

What problem does the IICO solve?

Traditional distribution methods, such as capped or uncapped sales, fail to guarantee both certainty of participation and certainty of valuation at the same time. In an IICO, a fixed amount of currency at the time of purchase buys at least a fixed fraction of the tokens in the sale.

Why is the IICO more transparent and fair than a traditional ICO?

The protocol provides participants with live market information, Buyers who purchase small amounts have similar purchase opportunities as whales.

Why is this user interface important? How is it making a difference?

The graphical UX/UI platform provides participants with the necessary tools and charts to make pricing judgements. Buyers can experiment with the available tools before committing to purchase ranges. Observers can monitor real-time bid statistics and earn rewards by poking bids in or out.
