If you want to know more, check out "Coin Interview with Ohad" on youtube. It's long but a very good explanation of what's being done here. A decentralized internet is the future, and many think Tau-Chain will build the best smart contracts. Ethereum cannot scale but it's all that we have now. ETH is sitting at 50$ a token now, so the upward pressure on Agoras as it gets more attention and is being utilized. I bought Agoras and don't regret...look into it before the next rounds of funding/publicity come as it will most likely continue to rise.
