Background
Bitcoin's market dominance recently hit a 2-year high, prompting an analysis of altcoin/BTC exchange rates. Historical charts reveal that even top-performing assets like Ethereum peaked against BTC within ~2 years of launch (2017) and never surpassed those highs again.
This study expands the scope to analyze historical exchange rate trends between BTC and 350 major altcoins.
Methodology
Data Selection:
- Top 500 coins by market cap (CoinMarketCap)
- Weekly price data from Gate.io (longest historical coverage)
- Excluded coins with <1 year trading history
Key Metrics:
- Calculated All-Time-High (ATH) and All-Time-Low (ATL) exchange rates against BTC
- Measured timeframes from launch to ATH/ATL
- Current rate vs. ATH ratio
Open-Source Approach:
- GitHub repository for transparent methodology
- Focused on basic statistical analysis (no complex modeling)
