A former NYSE market maker's read on moving averages: useful as trend filters and dynamic support, not as crystal balls — neutral but practical for traders.

• The core starter set is a 21 and 55 EMA plus the 200-day simple average, applied to any timeframe.
• Moving averages only follow price, and that lag is the point — they filter out noise instead of predicting.
• Bitcoin's 200-week average has marked the big bottoms: 2015, 2018, the 2020 crash, 2022, and the 2026 lows so far.
• The signals get strongest when a moving average lines up with a horizontal support or resistance zone.
• In sideways markets the lines tangle and every crossover fails, which is where most beginners lose money.

Outlook: Bitcoin's short-term trend has flipped up with price back above the 200-day average, which historically precedes longer runs — but choppy, rangebound stretches are where these tools break down.
