LAST WEEK’S News and Reports

◢ Hard Cap Has Reached

Since December 1, 2017 when the pre-sale started, we’ve had greater-than-expected interest from the community. By 00:00am EST, December 16 we’ve hit the hard cap of USD 60 million. The pre-sale closed earlier than expected.

We will contact all the successful participants of the pre-sale to confirm the wallet address and distribute NAS tokens. NAS will be listed on Huobi, Allcoin, Bcex and Lbank in the first half of January, with potentially many more major exchanges to come.

◥ Tsinghua University Talks Well-received

On December 14th, last Thursday, Nebulas CEO Hitters Xu and CTO Robin Zhu were in Tsinghua University at another Nebulas meetup to give talks and answer questions from Tsinghua Students.
