According to Mars Finance news, BCH issued a warning signal to Bitcoin traders about the halving. BCH is regarded as a leading indicator of the halving of the Bitcoin blockchain reward. After BCH completed its halving on April 4, its price has fallen 15% from its high to $604. Meanwhile, notional open interest in BCH perpetual contracts plunged 70% in seven days, and long bets are being unwound. Analysts believe that the trend of BCH indicates that Bitcoin may face selling pressure after the halving on April 20. JPMorgan predicts that BTC prices could fall back to $42,000 once the halving hype subsides. (Coindesk)
