Tau-Chain has no coins as for itself, but it comes with underlying facilities required for decentralized economy.
We plan to create Agoras, a decentralized intelligent economy with far going abilities and implications.
Agoras will have a currency and we pre-sale its coins now. There is a total amount of 42,000,000 intermediate coins (IDNI Agoras Tokens), that represent 100% of future Agoras coins. More details are given at this blogpost, and some more elaboration on Bitcointalk here and here.
IDNI Agoras (AGRS, Omni asset ID 58) are being traded on Bittrex.
Please don't hesitate contacting us for any question or in order to purchase outside of the exchange.
IMPORTANT: BEWARE OF FAKED TOKENS! ALWAYS VALIDATE THE ASSET ID!
