They had a very strong forecast platform, on technical and marketing side, we saw very strong projects there. But the ICO market has fallen.
I think they can also do a very strong de-fi project, we already saw their skills
To be honest I can't remember any projects that were developed on the Wings platform and are actually known or widely used today. Please point me to any of them.
Additionally, when it goes to develop any new "de-fi" project as you have described it, will be hard taking into consideration that the Wings team is almost not active anymore.
The reality in the crypto market changes very fast and today we have a totally different landscape as in 2017. ICOs are dead and that was the power that pushed projects like Ethereum and others on this hype, Wings took a decent share from the bubble pie but today the reality is different and I don't think Wings will achieve another success in actual state.
A total change is needed and in my opinion, it would be easier to start something new, as to continue this race on a really old and bad horse.
