What were your favorite coins prior to the 2017 crash that are now “dead”?

I was just thinking of all the hyped coins that were so promising at the time but never recovered.

Mine was Waltonchain. It was supposed to solve supply chain issues by placing inventory on a blockchain. Looked like it had a strong team. A lot of news. Videos of it working in real life. No one talks about it anymore.

Here were various Ethereum killers that failed to materialize and then there were coins like chain link and cardano that were sort of talked about that took off during the pandemic. Just interested in hearing what you guys were into.
