The team has gone, the product never meets its success in the crypto space. The problem is none of the investors tried to take legal action against this one. As far as i know, this project was getting around 2k bitcoin on its crowdsale a few years ago and i was also watching the progress on the ico.
There was no financial report about the fund since the development has been running. Decent already dead and this will never alive again.
On what grounds would they have sued them exactly? They delivered ton of stuff, it just seems no one was interested on their approach. You can't really force adoption even though they tried it trough hackhatons and stuff like that there was just too much competition and no one was interested about DCT.
