ICOs are a big gamble in general, but I do believe STOX is indeed a "safer" bet. STOX isn't trying to do something revolutionary or super original. But what makes them different is their planning and execution.
Their single goal is alot more humble -- to build a viable long-term business with STX coins as the primary currency. The potential use case is already there, and they already have an existing user base to become early adopters of the platform. Not to mention the hype and marketing.
They had these chess pieces in place BEFORE they even started the token sake. This tells me the team knows what they're doing. They know what it takes to build a successful business based on real-world experience, and not some empty promises outlined in fancy theoretical white paper. This is why I consider STOX to be a safer bet than Augur and Gnosis.
Well, Augur has already launched their beta. It's not super fancy though, but it's here. So, lets just hope Stox will keep up. I like both of them, but the actual product, it's UI/UX is what will matter. I subscribed to Stox newletters and hope we will be abe to try their platform by the end of the year!
