The STRK token is designed for network fees, staking (to help ensure consensus as the network decentralizes), and governance (voting via wrapped vSTRK).
SPX6900: the only part that feels good?
SPX6900 (SPX), a meme coin with tongue-in-cheek branding aimed at internet/financial culture, added about +14% (24h), extending a pocket of momentum in meme assets that have outperformed broader crypto today.
It is issued on Ethereum and trades largely on DEXs/launch platforms, positioning itself as an entertainment/community rather than a claim on a stock index. The project site explicitly disclaims any association with stocks or indices. In short, it’s a community narrative/utility first, and a financial index parody second. DYOR!
