Amazing how many once hot & high potential crypto experiments failed. Just a few on my list: - Fractional NFTs / ERC-404 - NFT lending - Music NFTs - Elastic supply tokens/stablecoins (although $AMPL still alive) - $YFI style 'fair launches' - (3,3) - Move-to-Earn (and similar Earn slogans) - Two-token model (Bera might be last to try it) - Algo-stablecoins (UST but sUSD depegged despite 750% col. ratio) - "Stable asset" controlled by interest rates, not pegged to fiat: $RAI - Stables backed by Protocol controlled value (PCV) like $FEI. (Olimpus DAO keeps similar Protocol Owned Liquidity (POL) idea alive.) Failure is part of innovation. And crypto is amazing as we experiment a lot. Perhaps those ideas were ahead of their time, like YouTube was before adequate internet speeds. Still, I feel innovation in tokenomics and demand for complex mechanics have declined. The UST collapse gave us PTSD. Experimentation still exists. e.g.: - Berachain's Proof-of-Liquidity (PoL) -> Chain-Owned Liquidity (COL) - Intia's Enshrined liquidity - Internet Capital Markets - Memecoin launchpads: Boop, pumpfun - L2s Remember that experimentation is great but don't marry your bags and the latest hot trend will likely fade away.
