In a official Reddit post...
...Joe Urgo (Co-founder of District0x) warns us about a fake site that looks exactly like the official district0x.io webpage.
The fake site claims there is a pre-sale of the fundraising event happening at July 18th.
There is no pre-sale available and no way to participate in the district0x fundraiser before the official start time at 3:00 PM UTC on July 18th.
