The past few days show an interesting picture: Bitcoin has barely increased by a couple of percent, while some small tokens have skyrocketed several times over. On the surface, everything seems logical — altcoins have a high beta coefficient, so they grow faster when BTC rises. But here’s the problem: the difference in growth sometimes amounts to dozens of times, and this can no longer be explained simply by the beta coefficient.

I looked into the numbers: the altcoin season index stands at 34, BTC dominance is at 58.5%. Both figures scream one thing — a true altcoin season has not yet begun. But here’s the paradox: in a market where there is no altcoin season, individual tokens move with an amplitude characteristic only of a full season. This is not a coincidence; it’s a sign of something else.

It turns out that the market capitalization of altcoins (excluding BTC and ETH) from December 2024 to April 2026 has decreased by about 40% — from $1.16 trillion to $700 billion. It sounds bad, but it creates a dangerous situation: when the market falls in half, the entry threshold for controlling the price also drops in half. Ten million dollars in a market with a capitalization of $50 billion is 0.02%, but in a $5 billion market, it’s already 0.2%. The money is the same, but the influence has increased tenfold.

Let’s take SIREN as an example. The token sharply soared at the end of March, but then analysts noticed: one entity controls up to 88% of the circulating supply. The price dropped from $2.56 to $0.79 in a day — a decline of more than 70%. Conservative estimates say that 48 wallets hold 66.5% of the circulating supply. This is not a market; it’s a container where small investors are trapped. SIREN is not an exception; it’s the norm for heavily fallen altcoins.

Now about the mechanics that amplify this volatility even more. When the price of SIREN was rising, the funding rate for shorts dropped to minus 0.3% every 8 hours — roughly minus 328% annually. Shorts pay longs just for holding their position. Over a month, such payments eat up more than 25% of capital, not counting losses from rising prices. At this level, shorts are not fighting a wrong forecast — they are fighting a machine that slowly wears them out.

Here’s what happens: the price rises, the losses of shorts grow, and when the loss reaches the margin call limit, the system automatically closes positions at the market price. This forced buying further pushes up the price, triggering new liquidations, and a chain reaction begins. In markets with thin liquidity, each trade causes significant movement. This is not growth; it’s a structured one-sided wear.

But here’s the interesting part: trading volume on DEXes on BSC increased by 97% year-over-year in a week. On-chain activity is indeed hot, but this is not an influx of new money — it’s an accelerated turnover of existing funds. Institutional flows confirm this. In early April, inflows into Solana ETFs almost dropped to zero, XRP ETFs show outflows. Ethereum ETF received $120 million, but the day before, there was a $71 million outflow. The picture is clear: institutional money is waiting, not switching to altcoins.

In 2021, it was different. Back then, BTC dominance fell from 70% below 40%, and the altcoin season index exceeded 90. It was a comprehensive growth supported by macro-liquidity, remnants of enthusiasm from the DeFi summer, and mass retail entry via FOMO. Continuous inflow of new money fueled the entire ecosystem. Now, 34 and 58.5% are a completely different story. The machine is just starting to warm up.

There is another key difference. Institutional funds via ETFs follow an asset allocation logic, not crypto market emotions. They set “rebalance BTC to X%,” not “altcoin season has started, let’s add positions.” These funds will not automatically flow into altcoins without a clear signal. In 2021, retail investors went where it was hot. Now, the anchor is institutional funds, and their path is fixed.

Returning to the beginning: Bitcoin grew by 1.83% over a few days, while small tokens jumped several times in the same period. Now the difference is clear. BTC growth is a macro pause, a level check, waiting for a signal. Explosive altcoin growth is a result of ultra-low capitalization after a fall, structural vulnerability, small capital in low-liquidity conditions, and extremely negative funding rates that turned shorts into fuel. Both phenomena happen simultaneously but tell different stories.

For a true altcoin season, BTC dominance must fall from 58% to about 39%, as it was in 2021. Institutional funds need to shift from a BTC-focused configuration to a diversified portfolio. Additional money must flow continuously, not be withdrawn. None of these points will be resolved by a 10% increase. BTC growth is a signal; sharp altcoin growth is an echo. By distinguishing these phenomena, one can avoid machine-predetermined decisions.
