Analysts are split on whether Bitcoin’s typical four-year cycle has ended in 2025, with institutional ETFs and regulatory shifts cited as key factors.

The four-year cycle, tied to Bitcoin (BTC) halving events, cuts miner rewards in half and reduces the supply of new Bitcoin entering circulation.
Historically, this was seen as the catalyst for a predictable pattern: accumulation, a post-halving bull run that peaked around 18 months later, followed by a sharp correction and multi-year bear market.
