Bitcoin (BTC) continues to set the pace of the market, but altcoins fail to keep up with that movement.
This is what the analysts at Altcoin Vector, a division of the Swissblock analysis firm, warn. they point out that The current environment is not favorable to position aggressively in alternative cryptocurrencies.
The analysis, published on April 22, 2026, shows a clear divergence between the behavior of bitcoin (BTC) and cryptocurrencies. “Bitcoin has risen higher. Altcoins have not really followed,” the report summarizes.
The central point is how altcoins react when bitcoin approaches key levels. Under normal conditions, when bitcoin tests resistance zones, it usually triggers a drag effect that boosts altcoins.
“Typically, BTC testing resistance helps altcoins fire up, with positive momentum rising above 25%,” SwissBlock explains.
However, this time that pattern did not hold. “The rally was brief, and negative momentum is trying to dominate,” the firm warns. To understand this dynamic, analysts shared a graph divided into two parts.
At the top you can see the price of BTC (yellow line) along with its support (blue line) and resistance (red line) levels. The blue circles mark moments in which BTC tests resistance, while the red ones indicate tests of support.
As CriptoNoticias has explained, in technical analysis, the term support is used to indicate an area where the price tends to stop its fall due to the appearance of buyers, while resistance is a level where there is usually selling pressure that limits price increases.
The chart shows that when bitcoin approaches resistance (as it did in January), altcoins typically react strongly. This is reflected at the bottom of the graph.
The indicator appears there “Altcoin Impulse“, which measures the momentum of the altcoin market. The blue line represents positive momentum and the red line represents negative momentum. The dotted line works as a reference: when the positive momentum exceeds that level, it indicates a clear expansion of the altcoin market.
But in the most recent stretch, that dynamic changes. Although BTC is approaching resistance again, the positive momentum of altcoins is weak and short-lived. The negative impulse quickly appears and dominates the structure.
This behavior indicates that altcoins continue to lag behind BTC. There is no sustained capital flow towards that segment, but specific movements that run out quickly.
“That tells you that altcoins are still lagging behind the rise of bitcoin,” the report notes. The implication is direct: without a clear breakout of bitcoin, the rest of the market fails to consolidate a trend. “For altcoins to improve, BTC probably needs to break out and consolidate,” the analysis adds.
In that sense, the firm concludes: “until then, this is not the best environment to deploy capital aggressively,” since short-term increases can quickly unravel.
