I saw a while back some talk in Komodo / SuperNET slack that *maybe* Fibre could be migrated over to a KMD assetchain, sort of a test case to learn the procedure in case other coins decide to migrate to get delayed PoW advantage and bitcoin level security that all assetchains on komodo platform get. That'd be a good outcome, but not sure if it actually gets off the ground, but some reason to remain hopeful. Time will tell, komodo devs are pretty awesome  so it's possible fibre lives again.
