2021 was a big year for altcoins as it was for Bitcoin. The altcoin season really began to heat up in January 2021 and extended into mid-May. The Altcoin index, which tracks the performance of 10 different cryptocurrencies, excluding Bitcoin, has gained over 566% during the first 4.5 months of 2021.

The altcoin rally was then interrupted by a brief sell-off that whipped out 65% of the previous gains. However, the sell-off only lasted for a month, and a new bullish cycle emerged in the second half of the year that culminated with the 6,707 high – an approximate 172% gain from June's bottom.

Year-to-date, the Altcoin index, which asses the strength or weakness of the broader altcoin market, has remained up over 331%.

To better assess the strength of the altcoin market, we can notice that predominantly the Altcoin index traded above the key 200-day simple moving average. Moreover, even during the pullbacks, the Altcoin index only briefly traded below the 200-SMA signaling a strong bullish cycle.
