LAST WEEK’S News and Reports

◢ NAS Token Exchange With Bonus Program a Complete Success

To give back to the Nebulas community and protect the interests of Nebulas supporters, Nebulas launched a Nebulas Token Exchange with Bonus Program starting from 3:00 a.m., November 25th. Last week the program was completed with a great success. Of the 5 million Nebulas tokens circulating in the community, 4,494,378 NAS tokens have been sent to our official wallet address and locked up.

The fact that nearly 90% of the tokens have been sent back showed the high degree of consensus of the Nebulas community.

After meetups in Silicon Valley, New York, Singapore and Shenzhen, Nebulas went on to hold two more in Shanghai and Beijing on December 9 and 10 respectively, with both event venues packed with interactive audience.
