Colletrix offered 5 beta watches on sale from 11th of June to 15th of June for $500 each. In the 5days period, Colletrix received 6942 applications. This figure is mind-blowing by any standard. Lets put this into proper perspective, this would have been a $3.4m sales in just 5 days. This fugure is even more than the total USD equivalent worth of CIPX tokens available for their planned IEO in july.
