Bitcoin's current chart patterns in 2025 are echoing fractals from the 2021 crash, with the cryptocurrency trading near $87,440. Analysts caution that if history repeats, Bitcoin could see a decline to $70,000. The 2021 peak of $51,700 was followed by a 34% drop, raising concerns about a similar downturn. Presently, Bitcoin's support is holding between $84,000 and $85,000. As the market anticipates a possible 2026 supercycle, altcoins may also experience volatility in response to Bitcoin's movements. Traders are closely monitoring these developments to gauge potential impacts on the broader cryptocurrency market.
