An excellent example of a fundamentally broken coin that nevertheless has a very vocal following is Vulcano ($VULC).
VULC has a good potential for growth and in the long term can be an excellent opportunity to invest, i recommend that you invest your assets in this cryptocurrency.
I believe you meant project that "was fundamentally broken". It indeed had a quite epic relaunch story. Because most of crypto don't have a real use case in the real world, we decided to go with the use case first and the result has been something that we are very proud of. It does not require millions of dollars in ICO money to do a crypto project that has innovative impacts in the world. It is only a matter of time that the wider crypto world learns of the VULC story.
The first Q&A video sums up the relaunch very well.
