If the price of Bitcoin is above the 50 MA and continues to rise, it may be seen as a good time to buy or hold onto Bitcoin as the trend is bullish. Conversely, if the price of Bitcoin is below the 50 MA and continues to fall, it may be a sign to sell or avoid Bitcoin as the trend is bearish.
Historically, 50 weeks MA played an important role in the last 2 cycles as well.
