Is altseason dead? Bitcoin ETFs rewrite crypto investment playbook

Bitcoin exchange-traded products may have fundamentally altered the concept of a crypto “altseason.”

For years, the crypto market followed a familiar rhythm, a near-predictable dance of capital rotation. Bitcoin (BTC) surged, bringing mainstream attention and liquidity, and then the floodgates opened to altcoins. Speculative capital rushed into lower-cap assets, inflating their values in what traders euphorically deemed “altseason.”

However, once taken for granted, this cycle shows signs of a structural collapse. 

Spot Bitcoin exchange-traded funds (ETFs) have shattered records, funneling $129 billion in capital inflows in 2024. This has provided unprecedented access to Bitcoin for both retail and institutional investors, yet it has also created a vacuum, sucking capital away from speculative assets. Institutional players now have a safe, regulated way to gain exposure to crypto without the Wild West risks of the altcoin market. Many retail investors are also finding ETFs more appealing than the perilous hunt for the next 100x token. Well-known Bitcoin analyst Plan B even traded in his actual BTC for a spot ETF. 

The shift is happening in real time, and if the capital remains locked in structured products, altcoins face a diminishing share of market liquidity and relevance. 

Is the altseason dead? The rise of structured crypto exposure

Bitcoin ETFs offer an alternative to chasing high-risk, low-cap assets, as investors can access leverage, liquidity and regulatory clarity through structured products. The retail crowd, once a major driver of altcoin speculation, now has direct access to Bitcoin and Ether (ETH) ETFs, vehicles that eliminate self-custody concerns, mitigate counterparty risk and align with traditional investment frameworks. 

Institutions have even greater incentives to sidestep altcoin risk. Hedge funds and professional trading desks, which once chased higher returns in low-liquidity altcoins, can deploy leverage through derivatives or take exposure via ETFs on legacy financial rails.

With the ability to hedge through options and futures, the incentive to gamble on illiquid, low-volume altcoins diminishes significantly. This has been further reinforced by the record $2.4 billion in outflows in February and arbitrage opportunities created by ETF redemptions, forcing a level of discipline into crypto markets that did not previously exist.

Will venture capital abandon crypto startups?

Venture capital (VC) firms have historically been the lifeblood of alt seasons, injecting liquidity into nascent projects and spinning grand narratives around emerging tokens. 

However, with leverage being easily accessible and capital efficiency a key priority, VCs are rethinking their approach. 

VCs strive to make as much return on investment (ROI) as possible, but the typical range is between 17% and 25%. In traditional finance, the risk-free rate of capital serves as the benchmark against which all investments are measured, typically represented by US Treasury yields. 

In the crypto space, Bitcoin’s historical growth rate functions as a similar baseline for expected returns. This effectively becomes the industry’s version of the risk-free rate. Over the last decade, Bitcoin’s compound annual growth rate (CAGR) over the past 10 years has averaged 77%, significantly outperforming traditional assets like gold (8%) and the S&P 500 (11%). Even over the past five years, including both bull and bear market conditions, Bitcoin has maintained a 67% CAGR. 

Using this as a baseline, a venture capitalist deploying capital in Bitcoin or Bitcoin-related ventures at this growth rate would see a total ROI of approximately 1,199% over five years, meaning the investment would increase nearly 12x.

While Bitcoin remains volatile, its long-term outperformance has positioned it as the fundamental benchmark for evaluating risk-adjusted returns in the crypto space. With arbitrage opportunities and reduced risk, VCs may play the safer bet. 

In 2024, VC deal counts dropped 46%, even as overall investment volumes rebounded in Q4. This signals a shift toward more selective, high-value projects rather than speculative funding. 

Web3 and AI-driven crypto startups are still drawing attention, but the days of indiscriminate funding for every token with a white paper may be numbered. If venture capital pivots further toward structured exposure through ETFs rather than a direct investment in risky startups, the consequences could be severe for new altcoin projects.

Meanwhile, the few altcoin projects that have made it onto institutional radars — such as Aptos, which recently saw an ETF filing — are exceptions, not the rule. Even crypto index ETFs, designed to capture broader exposure, have struggled to attract meaningful inflows, underscoring that capital is concentrated rather than dispersed.

The oversupply problem and the new market reality

The landscape has shifted. The sheer number of altcoins vying for attention has created a saturation problem. According to Dune Analytics, over 40 million tokens are currently on the market. 1.2 million new tokens were launched on average per month in 2024, and over 5 million have been created since the start of 2025.

With institutions gravitating toward structured exposure and a lack of retail-driven speculative demand, liquidity is not trickling down to altcoins as it once did.

This presents a hard truth: Most altcoins will not make it. The CEO of CryptoQuant, Ki Young Ju, recently warned that most of these assets are unlikely to survive without a fundamental shift in market structure. “The era of everything pumping is over,” Ju said in a recent X post. 

The traditional playbook of waiting for Bitcoin dominance to wane before rotating into altcoins may no longer apply in an era where capital stays locked in ETFs and perps rather than free-flowing into speculative assets.

The crypto market is not what it once was. The days of easy, cyclical altcoin rallies may be replaced by an ecosystem where capital efficiency, structured financial products and regulatory clarity dictate where the money flows. ETFs are changing how people invest in Bitcoin and fundamentally altering liquidity distribution across the entire market.

For those who built their strategies on the assumption that an altcoin boom would follow every Bitcoin rally, the time may have come to reconsider. The rules may have changed as the market has matured.
