In the first quarter of 2017, Ethereum (ETH) experienced a significant surge, with its price increasing from $8.19 on January 1, 2017, to $48.60 by March 31, 2017, marking a 493% increase over the quarter (source: CoinMarketCap). Similarly, in the first quarter of 2021, ETH's price rose from $737.88 on January 1, 2021, to $1,741.74 by March 31, 2021, reflecting a 136% increase (source: CoinMarketCap). These periods also saw heightened volatility in the altcoin market, with numerous altcoins experiencing substantial price movements.

The trading implications of these historical trends suggest that investors might anticipate similar volatility and potential growth in the altcoin market during the first quarter of 2025. According to @CryptoMichNL's tweet on January 6, 2025, the expectation is for a repeat of historical patterns. Traders should monitor ETH closely, as its performance could serve as a leading indicator for the broader altcoin market. Additionally, increased trading volumes and liquidity in altcoin trading pairs could be expected, with specific attention to ETH/BTC and ETH/USDT pairs due to their historical significance in market movements (source: CryptoMichNL).

Technical indicators during the first quarters of 2017 and 2021 showed bullish signals for ETH.

These metrics suggest that traders should watch for similar technical signals and volume increases in the current quarter to gauge potential market movements.
