On April 8, 2020, Bitcoin Cash Halving Occurs, Affecting Miner Economics. Bitcoin Cash undergoes its halving, reducing block rewards and causing many miners to see gross margins drop to near zero.
For Bitcoin's history, the Bitcoin Cash halving was relevant because it served as a preview of what might happen when Bitcoin's own halving occurred just one month later in May. The two cryptocurrencies shared the same mining algorithm (SHA-256), meaning miners could switch their equipment between Bitcoin and Bitcoin Cash depending on which was more profitable to mine at any given moment.
When Bitcoin Cash's block rewards halved, some miners found it more profitable to redirect their hash power to Bitcoin, which still offered 12.5 BTC per block for another month. This hash rate migration demonstrated the competitive dynamics between the two cryptocurrencies and highlighted concerns about what would happen when Bitcoin halved in May—would Bitcoin miners face similar profitability challenges, potentially reducing Bitcoin's network security?
