Methodology behind these forecasts

The projections shown above combine three statistical inputs: (1) the asset's tier-specific compound annual growth rate (log-CAGR calculated from the prior bull/bear cycles), (2) a sinusoidal modulation centered on the April 2024 Bitcoin halving, and (3) a volatility cone derived from the asset's 30-day realised volatility. The output is a probability band, not a point estimate: 50% of historical observations land inside the mid range, 74% inside the standard range, and 90% inside the wide range. None of this is investment advice — past performance does not guarantee future results, and cryptocurrencies can lose 70-90% of their value in bear cycles.

Risk considerations specific to this pair

Both assets are subject to crypto-specific risks: regulatory action, exchange counterparty failures, smart-contract exploits (where applicable), and liquidity drying up during macro de-risk events. Position-sizing matters more than predictions: a 1-2% portfolio weight in Arbitrum and the same in Optimism behaves very differently in drawdown than a 20% allocation.
