Bitcoin price analysis: BTC tests Bollinger Bands breakout as its creator flips bullish
CoinDesk
John Bollinger's fund has taken a bullish position in Bitcoin as the asset tests a Bollinger Bands breakout.Summary
John Bollinger, the creator of the Bollinger Bands technical indicator, announced on X that one of his investment fund's proprietary trading models has turned positive on Bitcoin, leading the fund to take a position in the asset. This comes as Bitcoin recently closed above its upper Bollinger Band on the daily chart, following its tightest-ever band reading—a phenomenon known as a "squeeze" that typically precedes significant price movements.
Currently trading above $80,000, Bitcoin's ability to establish a foothold above the upper band will serve as a key bullish technical signal. While the asset has risen approximately 9% over the last 30 days, it remains 36% below its October 2025 all-time high of $126,000.
