The year 2020 reshaped global perspectives on finance, technology, and resilience. As we stepped into 2021, the blockchain and cryptocurrency landscape was no longer a speculative frontier but a rapidly maturing ecosystem driven by real-world adoption, institutional interest, and technological evolution. While predictions in such a dynamic space are inherently uncertain, the consensus among 20 leading experts points to a transformative year defined by decentralization, scalability, and mainstream integration.
Core Trends Shaping 2021
The pandemic accelerated digital transformation across sectors, spotlighting inefficiencies in traditional systems. Blockchain emerged as a critical tool for enhancing transparency, security, and efficiency — especially in healthcare, supply chains, and financial services. At the same time, unprecedented monetary stimulus from governments fueled inflation concerns, driving renewed interest in Bitcoin as a digital gold and hedge against economic instability.
Institutional adoption gained unstoppable momentum. Companies like MicroStrategy, Square, and PayPal invested heavily in Bitcoin, while financial products such as Grayscale’s Bitcoin Trust and CoinShares’ ETPs signaled growing legitimacy. Meanwhile, decentralized finance (DeFi) exploded in value and innovation, offering permissionless lending, borrowing, and yield generation.
These developments laid the foundation for 2021 — a year where blockchain would move beyond theory into practical, scalable applications.

Expert Predictions: What Leaders Expected in 2021
Brian Behlendorf, Executive Director, Hyperledger
Behlendorf emphasized that volatility would remain intrinsic to crypto markets. However, he foresaw steady growth in enterprise blockchain adoption, particularly through collaborative networks like IBM’s Food Trust. He predicted that by the end of 2021, most industries would either have or be building DLT-based transaction networks. Open governance and ease of access would determine which blockchain consortia succeeded.
Brian Brooks, Former Acting Comptroller of the Currency
Brooks compared crypto’s trajectory to the early internet — once limited to technologists, now becoming universally accessible. He anticipated 2021 as a tipping point for mass adoption, provided the industry addressed compliance challenges like anti-money laundering (AML) and fraud prevention. Interoperability between platforms, he argued, was essential for long-term success.
Da Hongfei, Founder of Neo and Onchain
Da believed 2021 would mark blockchain’s entry into the mainstream. With Bitcoin proving its value to institutional investors and DeFi showcasing transformative potential, he expected continued acceleration in adoption across finance and beyond.
Denelle Dixon, CEO, Stellar Development Foundation
Dixon highlighted Stellar’s focus on user-friendly, interconnected products. She predicted increased corporate adoption of blockchain for cross-border B2B payments and C2C remittances. By expanding partnerships with fiat token issuers and payment gateways, Stellar aimed to position blockchain as a scalable solution for global finance.
Elissa Shevinsky, Former Product Lead at Brave
Shevinsky saw 2021 as an extension of 2020’s trends — more investment in crypto from well-funded players, sustained media attention on Bitcoin, and rising distrust in centralized institutions due to fiscal mismanagement and cyberattacks. This erosion of trust, she argued, strengthened the case for decentralized alternatives.
Emin Gün Sirer, CEO, AvaLabs
Gün Sirer predicted DeFi would evolve into a multi-chain ecosystem, with users leveraging cross-chain bridges to maximize yields. He also emphasized the importance of true decentralization and on-chain governance, noting growing awareness of centralization risks in many blockchains. Enterprises, he added, would begin building real applications on customizable, high-performance platforms.
Heath Tarbert, Former CFTC Chairman
Tarbert viewed digital assets as part of a broader macro trend toward market digitization. He stressed the need for principle-based, coordinated regulation to support innovation while protecting consumers. The potential of blockchain to eliminate geographic barriers in finance was undeniable.
Irene Gao, Regional Sales Director, Bitmain NCSA
Gao noted a shift from retail speculation to institutional integration. With postponed mining operations resuming — especially in the U.S. — she expected greater geographic diversification in Bitcoin mining. Bitmain’s improved customer support and extended warranty periods reflected growing professionalism in the mining sector.
Jean-Marie Mognetti, CEO, CoinShares
Mognetti anticipated a parabolic rise in Bitcoin prices if momentum continued. He expected institutional demand to outpace new supply, with products like ETPs buying more BTC than miners produced daily. This structural shift could drive a more stable — yet powerful — bull run compared to 2013 or 2017.
Jimmy Song, Blockchain Educator
Song offered a contrarian view, suggesting little real change would occur beyond attracting new investors. He remained skeptical of altcoins, viewing most as scams compared to Bitcoin’s proven value proposition.
Joseph Lubin, Ethereum Co-Founder
Lubin predicted DeFi would become more accessible to everyday users through improved interfaces. He also highlighted progress toward Web3 integration — combining decentralized storage (e.g., IPFS), bandwidth, and value layers. With ETH2.0 research advancing and tools like Infura supporting the beacon chain, Ethereum’s scalability upgrades were poised for significant progress in 2021.

Mance Harmon, CEO, Hedera Hashgraph
Harmon identified three converging trends: tokenization, DeFi, and business logic moving to Layer-2 solutions. This convergence would enable enterprises to use public DLT networks while maintaining privacy and compliance via hybrid architectures. Use cases like invoice factoring and inventory financing would be transformed by these innovations.
Mathew Yarger, Head of Mobility & Automotive, IOTA Foundation
Yarger described 2021 as a transition year — from seeing DLT as a panacea to recognizing it as a practical tool. Interoperability between permissioned and permissionless systems, integration with IoT and cloud environments, and real-world testing in regulated sectors like healthcare and energy would define progress.
Mike Belshe, CEO, BitGo
Belshe believed institutions increasingly recognized Bitcoin’s scarcity-driven value. With pandemic effects lingering and institutional inflows rising, he expected 2021 to be a record year for both retail and institutional participation in crypto.
Paul Brody, EY Global Innovation Leader for Blockchain
Brody forecasted enterprise adoption of Ethereum mainnet and early use of privacy-preserving DeFi. He highlighted rapid improvements in DeFi security tools and predicted early adoption of decentralized enterprise apps outside finance. The shift from DApps to Zapps (zero-knowledge applications) would enhance user privacy.
Roger Ver, Bitcoin.com Founder
Ver maintained his long-standing optimism: every year had been better than the last — and 2021 would be no exception.
Samson Mow, Chief Strategy Officer, Blockstream
Mow predicted strong Bitcoin performance driven by institutional demand but warned of a surge in low-quality altcoins targeting retail investors seeking quick gains.
Scott Freeman, Co-Founder & Partner, JST Capital
Freeman expected continued growth in decentralized credit and derivatives over the next 18 months. He noted a shift in investor mindset — viewing Bitcoin as digital gold while evaluating other cryptos based on utility rather than speculation.
Vinny Lingham, CEO, Civic
Lingham called 2020 a “warm-up” for 2021. He predicted explosive growth in decentralized storage (e.g., Filecoin), DeFi, and non-political money. For sustained success into 2022, he stressed the urgent need to solve Ethereum’s scalability challenges.
