Bitcoin's post-halving rally hit a snag on April 22 as automated trading algorithms sold off the cryptocurrency. Despite reaching weekly highs of $66,546, Bitcoin faced stiff resistance with buyers outnumbered. Analyst Matthew Hyland noted that Bitcoin's 10-week simple moving average (SMA), a key bull market support line, stood at $65,686. Meanwhile, trader Credible Crypto suggested that Bitcoin's price could drop again to liquidate long positions before a definitive upward reversal. Open Interest was already on the rise, indicating a potential move back down.
