Cardano rivals like Avalanche, Solana, Polkadot, NEAR, and Algorand are gaining market share as Ethereum faces scalability challenges.
Cardano (ADA) Tops $0.70 as Founder Predicts Ethereum Collapse
Cardano (ADA) recorded a weekly gain of 12.2%, closing above $0.70 on April 26 — its highest since February 2025.
The move follows public remarks by Cardano founder Charles Hoskinson, who stated during a CNBC interview that Ethereum’s scalability and governance limitations are likely to undermine the network within the next 15 years.
Hoskinson, an original co-founder of Ethereum, highlighted issues around layer-2 reliance, decentralization trade-offs, and ecosystem fragmentation as critical vulnerabilities.
“Without fundamental reform, Ethereum risks disintegration by 2040,” Hoskinson said, citing longstanding market concerns regarding the network’s technical roadmap.
Ethereum’s transition toward rollups and modular scaling, including recent updates such as Dencun, has not eliminated bottlenecks related to cost and throughput.
These factors has seen Cardano rivals like Solana, Avalanche and a handful of others gain ground on Ethereum in recent weeks.
Cardano Rivals to Watch if Ethereum Collapses by 2040
Notably, Charles Hoskinson founding member of Ethereum before exiting to found Cardano. Hence its unsuprisingly that his prediction of Ethereum’s collapse weighs heavy on market sentiment.
If Ethereum continues to lose market share, Avalanche, Solana, Polkadot, NEAR Protocol, and Algorand are some 5 Cardano rivals to watch in the months ahead, based on recent price trends, ETF filings and institutional demand for these assets.
Avalanche (AVAX)
-
Current AVAX Price: $22.43, up 12% for the week.
-
VanEck’s spot Avalanche ETF filing entered SEC review in April 2025.
-
Avalanche’s high transaction throughput, customisable subnets, and enterprise integrations strengthen its case as a scalable smart-contract platform.
Solana (SOL)
-
Current SOL Price: $149.23, up 6.9% for the week.
-
Solana ETF applications by Franklin Templeton, Grayscale, and VanEck remain under SEC evaluation, with decision deadlines in October 2025 according to Bloomberg chief ETF analyst Eric Balchunas.
-
Solana’s fast transactions through-put and growing decentralized finance (DeFi) traction continues to drive institutional and developer interest.
Polkadot (DOT)
-
Current Polkadot Price: $4.27, up 10% for the week.
-
Nasdaq submitted an application to list a 21Shares Polkadot ETF, pending SEC approval.
NEAR Protocol (NEAR)
-
Current Price: $2.64, up 21% for the week.
-

-
21Shares listed Algorand ETPs across European exchanges, but no current U.S. ETF filings.
In summary:
Hoskinson’s assessment of Ethereum’s future emphasizes growing concerns surround the long-term viability of the pioneer smart-contract blockchain network. Despite a leadership shuffle at the Ethereum Foundation in early March 2025, key on-chain benchmarks like scalability, governance, and decentralization resilience remain clouded under pesimism.
As regulatory clarity improves and technological differentiation widens, Cardano rivals like platforms like Avalanche, Solana, Polkadot, NEAR, and Algorand, able to meet those demands are expected to gain market share.
