For the last several months, BTCUSD hasn’t moved much in relative terms to historical price action, resulting in a lull in the cryptocurrency’s characteristic volatility. That lull is evident in how tight and narrow the Bollinger Bands are on the 2-week timeframe.

The Bollinger Bands are the second-tightest in the history of crypto | BTCUSD on TradingView.com
According to Bollinger Band – a measure of how wide or narrow the Bollinger Bands are at any given moment – Bitcoin is at the second-tightest the bands have ever been. In other terms, volatility is the second-lowest ever on the 2-week timeframe.
The only time the bands were ever this tight before, was in 2015 and the number one crypto asset by market cap went on to rally by 7,500%.
Is An Explosive Bull Rally Coming Soon To Crypto?
Bollinger Band Width only shows one side of the story: volatility at historical lows. It says nothing about the direction Bitcoin might take.
The Bollinger Bands themselves consist of a 20-period simple moving average and two standard deviations. After the bands contract, they expand to release and extreme build up of energy. Simply put, when the bands expand, the breakout will be powerful – strong enough to set the trend.

Currently, the 2-week Bollinger Bands are above the mid-line, suggesting that the direction is up. Holding above the level in the past has resulted in some of the largest bull runs in crypto.

In a surprise bounce from last Friday’s under $20,000 retest, Bitcoin held its fourth consecutive candle close above the middle-Bollinger Band and is now making a move higher.
BTCUSD is up 20% already in the last 72 hours. If the Bollinger Bands start to expand, the rally might not stop for some time.
