A2A TOKEN description
A2A is token that will give you a chance to reduce your trading fees by up to 50% through paying commissions with it, and will increase your discount based on the amount of the commissions paid to the system and on the amount of time that you hold the token on your account. If you want a proof of concept - please have a look at BNB Binance token which has a similar structure and purpose.
To match cryptocurrency market growth, we also have a mechanism that balances the prices of A2A token. From every commission paid to STeX, 70% of A2A are sold on the open market and become STeX's income. The remaining 30% are transferred to the smart-contract known as A2A-SHOP to be sold from that contract at an increasing price. When the price of A2A goes down (and it will at some point, as it is a free market), the circulation supply will be reduced every day by the 30% from daily commissions paid to the exchange. Lower A2A prices will result in bigger absolute amounts of A2A transferred to the smart contract. In an extreme case, the demand for A2A, needed to be bought to process the ongoing transactions, can exceed the total circulation supply and the price will immediately rise to the level of the current sale price in the A2A-SHOP. This system gives us an assurance that any A2A dump will be simply a perfect trading opportunity, and the token itself might become a very attractive trading instrument.
We are going to make an airdrop for all STE token holders in amount of 10% from final supply of the A2A tokens so you can start trading on STeX without commissions.
We do not like the idea of any changes in our STE specs so it will stay with the same rights and functionality as before, no changes. We would like to put your attention to the fact that only STE token holders will be sharing the profits. A2A tokens will not affect the final amount of commissions received by the STE holders.
