Take note, these people who called ATS a SCAM are mostly parasitic bounty hunters not investors. The ATS team is doing their best to rectify this mistake and for the past two weeks paid most of the Bounty Hunters specially those who referred a lot of people and got thousands of ATS tokens.
The lie was repeated again by another insolent investor.
Just because you missed out doesn't mean the entire project is a scam. They seem to have the entire concept worked out, put a lot of thought and attention to their whitepaper and had a successful ICO - up until the signup bonus which was added at the last moment. One mistake doesn't mean this project should fail, it just means it'll have a rocky start with prices being way belong the indication. But as long as they'll deliver their product, which I believe they will eventually, prices will rise again.
