Well Kaspa developement looking good, also thier tech, Sompolinski and Sutton got some breakthroughs with thier GhostDAG. They just launched 10BPS on testnet and in couple of weeks its comming to mainnet, will be fastest chain around, also smart contract incoming and they next level too based rollups, zkEVM, thier L1 will be used as sequencer and L2 will pay fees with $KAS to L1, aka non parasitic SC, unlike like other ETH L2 use own coin and sentralized sequencers. I mean its definetely not a scam, or hype driven, they got tech and research papers to back it up.
