Blockstream CEO Adam Back renewed his long-standing criticism of altcoins and memecoins, saying market efficiency may finally catch up with assets he considers weak.
summary
- Adam Back said efficient markets could eventually lead to many altcoins and memecoins being priced near zero.
- Bitcoin dominates at nearly 59%, keeping pressure on the broader altcoin market turnover this month.
- Nearly 40% of altcoins were trading near all-time lows, showing weak risk appetite outside of Bitcoin.
Buck wrote on X that he expected the efficient market hypothesis to push altcoins toward “zero dollars.” He added that he made a similar call about a decade ago and was surprised that it took so long for the markets to catch up with “air tokens, altcoins, meme coins, etc.”
The efficient market hypothesis is the idea that asset prices reflect available information. Back used this framework to argue that many tokens that have no clear long-term value may eventually lose market support.
Buck’s comments reflect a view often held by Bitcoin-focused investors. They argue that Bitcoin’s fixed supply, security model, and long track record make it different from other crypto assets.
Bitcoin dominance keeps pressure on altcoins
This warning comes as Bitcoin continues to absorb a significant share of the cryptocurrency market’s attention. Crypto news I mentioned The total market cap of cryptocurrencies is approximately $2.7 trillion, with Bitcoin dominating at approximately 59%.
Bitcoin’s high dominance often limits the momentum of altcoins. When capital remains concentrated in Bitcoin, smaller tokens tend to see shorter rallies and steeper drawdowns.
Crypto.news too I mentioned In December, altcoins were still below key long-term moving averages while Bitcoin dominance remained near the 58% to 59% range. This analysis said capital has not yet shifted aggressively to the broader altcoin market.
Memecoins face a more stringent test
Back also mentioned memecoins, a segment of the market often driven by online interest rather than revenue, protocol fees, or direct utility. These tokens can move quickly during risk phases but often decline further when liquidity becomes tight.
Memecoins are usually inspired by internet memes or trends and are notorious for volatility. This profile makes them more vulnerable when traders underestimate risks.
The market is still supporting some large meme coins. Crypto.news data showed the token category has a market cap of over $34 billion, led by names like Dogecoin, Shiba Inu, and Pepe.
This does not settle the debate about long-term value. This shows that memes still have active liquidity, even as critics say many of them lack lasting demand.
Altcoin Season still needs to be confirmed
crypto.news I mentioned In March, nearly 40% of altcoins traded near all-time lows. The same report said that Bitcoin dominance remained high, which means that the shift to altcoins has not clearly begun yet.
This context makes Buck’s comments timely. The breadth of weak altcoins gives Bitcoin-focused investors more room to argue that the market is separating stronger assets from weaker tokens.
A full altcoin recovery will likely require Bitcoin stabilization, reduced dominance, and improved risk appetite. Without these conditions, traders may continue to prefer Bitcoin and a smaller pool of liquid tokens with significant value.
