- This prediction is heuristic and not financial advice. Market conditions can change rapidly.
- Unforeseen global macroeconomic events can override specific crypto-related factors.

- If regulatory sentiment shifts negatively, especially in key markets, predictions could be adversely affected.
- Success of the underlying cryptocurrency project and its technology remains a fundamental factor.
