I think stack still needs to deliver on the promises and the products that were promised during the ico or may be the project team is intentionally delaying development due to bad market conditions, i know stk is lacking volume and value in the market but that can be improved only by providing real solid products as promised.
Agreed, would be more impressed if your developers were working on delivering a working product that allows people to spend their crypto in retail stores. That is what all the investors put their money in for, not to pay them for burnishing their resume by participating in other peoples hackathons.
