Crypto Founder Explains Why ‘Altcoin Season’ May Not Return the Way It Used To

• The crypto sector faces a structural crisis after six years of decline, where $4 trillion valuations hid a lack of actual incoming capital.
• Projects with locked supplies of up to 90% allowed teams and insiders to manipulate prices and extract liquidity from current retail investors.
• The Altcoin Season Index currently stands at 41 points, remaining far from the peak of 78 reached in September 2025.

The co-founder of Glyde, known as Sweep, issued a stark warning regarding the future of Altcoin Season. The expert explained that the sector’s problems are not macroeconomic, but rather structural distribution flaws.

Altcoins aren't coming back and it has nothing to do with macro. The industry has been dying for 6 years and this cycle was the final distribution

The bubble wasn't in price, it was in valuation. Every number you've seen this cycle was a lie and the total crypto market cap at…

Market cap figures of $4 trillion are—according to Sweep—an illusion created by locked supplies and manipulated prices. The real money that entered the ecosystem represents only a fraction of the values officially reported.

A token with a $2 billion market cap and only 5% float possesses only $100 million in tradable value. The rest is team inventory that constantly exerts downward price pressure.

Technical analysis reveals that the extraction pattern begins with launches where 90% of the supply remains locked. This allows for the presentation of massive fully diluted valuations (FDV) that do not correspond with the real liquidity on the books.

Subsequently, market makers use loans and options to generate artificial movements in thin order books. This tactic aims to attract retail liquidity before teams sell their positions during rallies.

Extraction Engineering and Investor Exhaustion

The process culminates in a phase where short traders are lured into paying negative funding rates. In this way, protocols collect fees from the very traders trying to bet against the overvaluation.

Because supporting capital is sold during upturns, projects fail to recover after crashes. This lack of rebound is what differentiates the current cycle from historical bull markets.

The current Altcoin Season Index shows a slight recovery from the low of 12 recorded in April 2025. However, Bitcoin dominance remains the prevailing force in the digital financial landscape.

Despite the crisis, specific assets like SIREN and DEXE saw gains of up to 872%. These exceptions confirm that capital is now seeking highly specific niches instead of a generalized surge.

Sweep maintains that this collapse is a necessary cleanup for the crypto ecosystem. Only the elimination of these extractive models will allow for a genuine recovery based on utility and real capital, not engineering.

Historically, altcoin structures favor insiders over the public. The end of the traditional Altcoin Season paves the way for a stage of greater transparency and maturity in the markets.
