0.0001 ETH per 1 A2A -- maybe.

A few current details about the A2A ICO can be seen at http://stex.exchange/news - pasted below. As you can see they are saying "we can set the affordable price at 0.0001 ETH per 1 A2A", but that doesn't mean that it's set in stone.

UPCOMING A2A ICO ANNOUNCE

Dear STeXers!

To meet the requirements and fit into regulations restricting security tokens to be promoted, we have come up with a solution to solve this problem. Instead of creating a liquidity pool in exchange for the STE tokens, we have decided to create liquidity by offering our internal token for public use. Originally, it was used as an intermediary in every trade on STeX using A2A technology. The problem is that you need a measurement system to evaluate all the tokens to create cross-rates, and we used an additional token for that purpose.

Furthermore, we have a promotional system to attract users and make their trading activities more profitable (especially, for active traders who may suffer from turnaround commissions).

By mixing these two concepts together, we have created a STEX utility token named A2A after the technology Any2Any we invented and use to support over 10,000 sross rates.

The main utility function of this token is to provide an easy to account tier system for commission discount for all users on the STeX exchange. Clearly, there are no passive income opportunities, no profit sharing in the new token, and, at the same time, it should be very attractive for the users to buy, use and hold in order to get extra discounts and unlock the professional features on STeX. Yes, we have professional tools in our system, and yes, they are consuming the resources, so, they will be available only for professional traders with a sufficient amount of commissions paid to the system.

There was also a problem with the STE price which became expensive in USD terms.

The new A2A tokens will have no connection with the STE and, therefore, we can set the affordable price at 0.0001 ETH per 1 A2A or so.
This utility token also allows us to make the deals with some ICO promo platforms and this process will start as soon as A2A whitepaper is ready.
We will revise the information on our website, social media and chatrooms, thus, it will be promoting the project per se and upcoming A2A ICO.

Good news is that the general marketing agreement with PR company was signed last week using this new concept and we expect to see results very soon. During this week our website will be updated and the first media coverage will appear right after that.

All details about A2A token will be published soon.
