Zcash development company ECC: Considering switching Zcash from PoW to PoS mechanism

According to Chain News, the Electric Coin Company (ECC), the developer of Zcash (ZEC), published an article titled "Should Zcash switch from Proof of Work to Proof of Stake?", saying that it is considering switching Zcash from Proof of Work (PoW) to Proof of Stake (PoS) mechanism. Because currently in PoW, miners must sell their mining output to cover costs (electricity costs and ASIC mining machine costs), which causes continuous downward pressure on the price of ZEC, generating about $100 million in selling pressure in the past year. In PoS, everyone can keep ZEC for Staking, thus becoming a long-term investor, while also providing better security and performance at a lower cost.
