#SCASH is not meant to "replace" Bitcoin, but to provide a parallel experiment: in an era completely monopolized by ASICs, proving whether a CPU-friendly + Bitcoin-level security model is sustainable. The project is anonymously led by former Zcash core developer (bitcartel/Simon Liu), who previously promoted Zcash's anti-ASIC efforts and later left due to ideological differences.
Of course, as an early pure community project, the risks are very real: low liquidity, high price volatility, small network size, and no institutional endorsement. It is suitable for technical players who have faith in the idea of decentralization and enjoy hands-on mining, rather than speculators seeking quick riches.
If you are a CPU miner, you might want to try running a node or mining a bit; this could be the closest opportunity to the "2009 Bitcoin home computer mining" era. https://t.me/SatoshiCashNetwork
