Blockstream CEO Adam Back has renewed his long-running criticism of altcoins and memecoins, saying market efficiency may finally be catching up with assets he views as weak.
Summary
- Adam Back said efficient markets may eventually price many altcoins and memecoins near zero.
- Bitcoin dominance near 59%, keeping pressure on broader altcoin market rotation this month.
- Nearly 40% of altcoins traded near all-time lows, showing weak risk appetite outside Bitcoin.
Back wrote on X that he had expected the efficient market hypothesis to push altcoins toward “$0.” He added that he made a similar call about a decade ago and was surprised it had taken this long for markets to catch up with “air tokens, altcoins, memecoins etc.”
The efficient market hypothesis is the idea that asset prices reflect available information. Back used that framing to argue that many tokens without clear long-term value may eventually lose market support.
Back’s comments reflect a view often held by Bitcoin-focused investors. They argue that Bitcoin’s fixed supply, security model, and long record make it different from other crypto assets.
Bitcoin dominance keeps pressure on altcoins
The warning comes as Bitcoin continues to absorb a large share of crypto market attention. Crypto.news reported that the total crypto market cap was around $2.7 trillion, with Bitcoin dominance near 59%.
High Bitcoin dominance often limits altcoin momentum. When capital stays concentrated in Bitcoin, smaller tokens tend to see shorter rallies and sharper drawdowns.
Crypto.news also reported in December that altcoins were still below key long-term moving averages while Bitcoin dominance stayed near the 58% to 59% range. That analysis said capital had not yet rotated strongly into the broader altcoin market.
Memecoins face a tougher test
Back also mentioned memecoins, a market segment often driven by online attention rather than revenue, protocol fees, or direct utility. These tokens can move quickly during risk-on phases but often fall harder when liquidity tightens.
Memecoins are usually inspired by internet memes or trends and are known for volatility. That profile makes them more exposed when traders reduce risk.
The market still supports some large memecoins. crypto.news data showed the meme token category with a market cap above $34 billion, led by names such as Dogecoin, Shiba Inu, and Pepe.
That does not settle the long-term value debate. It shows that memecoins still have active liquidity, even as critics argue many lack durable demand.
Altcoin season still needs confirmation
crypto.news reported in March that nearly 40% of altcoins were trading near all-time lows. The same report said Bitcoin dominance remained high, meaning rotation into altcoins had not yet clearly started.
That context makes Back’s comments timely. Weak altcoin breadth gives Bitcoin-focused investors more room to argue that the market is separating stronger assets from weaker tokens.
A full altcoin recovery would likely need Bitcoin to stabilize, dominance to fall, and risk appetite to improve. Without those conditions, traders may continue to favor Bitcoin and a smaller group of liquid large-cap tokens.
