Every now and then, Bitcoin takes a back seat in the multi-trillion-dollar crypto market. Its place at the wheel is temporarily taken by a wide range of cryptocurrencies from large-cap projects like Ethereum to small, new meme coins. They embark on a tumultuous ride better known as the altcoin season, when any crypto can surge 1,000% in one day and disappear into obscurity the next.
The crypto market moves in cycles, with the altcoin season among the most profitable periods. This is the time when money flows out of Bitcoin into smaller, alternative cryptocurrencies (altcoins). It is a period marked by intense volatility that many short-term traders thoroughly enjoy. However, the signs of an upcoming altcoin season are not always the same or come at the same time.
This guide will explain exactly what altcoin season is, break down the key indicators that signal its arrival, and provide a checklist to help you prepare for the next one. In the end, you will understand better when to join the ride, when to buy crypto, and when to step off.
Bitcoin was the first cryptocurrency. All the other coins that came after it are alternative coins to Bitcoin. Simply put, any other cryptocurrency than Bitcoin is an altcoin. The best-known altcoins include large-cap projects like Ethereum, stablecoins like Tether, meme coins like Dogecoin, or privacy coins like Monero.
Bitcoin is the largest cryptocurrency by market capitalization. Its influence over the rest of the crypto market is particularly strong for almost the entire year, and less during the altcoin season. Due to its prominence, Bitcoin represents a safe haven for investors seeking to preserve long-term crypto holdings.
The altcoin season marks a period in the market cycle where altcoins, as a group, outperform Bitcoin. During this time, traders start withdrawing money from Bitcoin and pouring it into other coins, including established altcoins, new projects, meme coins, speculative tokens, and rising assets with potential for high returns.
Generally, the altcoin season is characterized by a mix of euphoria, FOMO (Fear Of Missing Out), and explosive price action across the board.
Here’s where the altcoin season fits in the crypto market’s four-stage cycle:
Money flows into Bitcoin. The BTC price rises first, and its dominance increases. During this phase, altcoin prices are low, and investor sentiment is often negative.
Money flows from Bitcoin to large-cap altcoins, kick-starting the altseason. Ethereum and other top altcoins start to outperform Bitcoin. This stage sees an increase in investor interest and optimism.
Money is flowing from large caps to mid- and small-cap altcoins. This is the peak of altcoin season, when smaller, riskier projects see parabolic gains. Significant market transitions are underway now as some investors sell their assets, often for substantial returns. Others enter the market in a last-ditch attempt to secure some gains.
This period, also known as the Cool-Down, displays a downtrend as prices decline and panic engulfs investors. Selling pressure increases as participants become anxious about the market’s future. The market tops out, and money flows back to the safety of Bitcoin or stablecoins. The altcoin season ends.
The altcoin season does not begin or take place every year at the same time. However, you can anticipate it by studying the market, particularly these key indicators:
BTC dominance is the percentage of the total crypto market capitalization that is held in Bitcoin. It is the most important indicator of when the altcoin season starts. For example, a steady drop in BTC.D indicates that investors are withdrawing funds from Bitcoin and rotating them into altcoins. You can track the BTC.D chart on platforms like TradingView.
This metric is another quick indicator of whether an altcoin season is underway. The rule to determine it is simple: if 75% of the Top 50 altcoins have outperformed Bitcoin over the last 90 days, it’s officially altcoin season.

The ETH/BTC trading pair is a key barometer for the market, including the altseason. A rise in the ETH/BTC chart shows that the leading altcoin is outperforming Bitcoin. At this point, most traders declare the altcoin season open.
The altcoin season could be a make-or-break period for your crypto portfolio. If you let FOMO or hype lead you, you might fund speculative projects that fail to deliver the high returns they promise.
Your best strategy to thrive in the altcoin season is to maintain emotional control and use these simple tips:
You can’t buy everything. Research the 10-20 promising projects across different crypto niches that you want to buy when the time is right. Analyze the market and check the crypto news today. These altcoins may range from meme coins to AI crypto, privacy coins, or gaming, among others.

Most coins emerging during the altcoin season are not ideal for long-term holdings. Altcoin seasons are euphoric, but they don’t last forever. Have a clear plan for taking profits on the way up.
During the peak of altseason, markets move fast. You need an exchange with deep liquidity and a reliable trading engine.

According to BlockChainCenter, it is not altcoin season now. Bitcoin dominance is still high. The Top 50 altcoins have not outperformed Bitcoin over the last 90 days. Also, the ETH/BTC chart is not favorable to Ethereum. These key indicators show that we are outside the altseason. Monitor them periodically to better understand the change in market cycle phases.
The altcoin season can be a lucrative period, but it also involves considerable risks. Analyze the market, research projects, and do your due diligence before jumping into crypto trading during this period. Get your strategy ready and open a Bitunix account to capitalize on the next altseason.
