Three Financial Giants Predict Why Crypto Faces Its Hardest Test Yet In 2026

What Happened

Throughout 2025, BeInCrypto spoke with veteran investors and leading economists to assess where the crypto industry is headed and what lies ahead for a sector long defined by uncertainty.

Shark Tank investor Kevin O’Leary starts from a simple premise. As institutional capital moves in, crypto shifts away from endless token hunting and toward a narrow set of assets that can justify long-term allocation.

In that environment, crypto investing shifts away from speculation and toward disciplined portfolio construction, closer to how traditional asset classes are managed.

But even as investors narrow their holdings, the issue of who ultimately controls crypto’s monetary rails is becoming more complicated.

While investors like O’Leary focus on narrowing exposure, Greek economist and former finance minister Yanis Varoufakis pointed to a different shift.

“As we speak, there are Malaysian companies, Indonesian companies, and companies here in Europe that increasingly use Tether… which is a huge problem. Suddenly, these countries… end up with central banks that do not control their money supply. So their capacity to effect monetary policy diminishes and that introduces instability,” Varoufakis said in a BeInCrypto podcast episode.

Market Context

This year, crypto looked less like an experiment and more like a maturing market, shaped by institutional consolidation, faster-moving regulation, and growing macroeconomic pressure.

Institutional Capital Forces Crypto Consolidation

“If you statistically look at the volatility of just Bitcoin and Ethereum and a stablecoin for liquidity… That’s all I need to own,” O’Leary told BeInCrypto in a podcast episode.

That framework informs his outlook for 2026. As regulation advances and institutional participation deepens, O’Leary expects capital to concentrate around Bitcoin and Ethereum as the market’s core holdings. Other tokens will struggle to justify sustained allocation and will compete largely on the margins.

He linked this approach to the logic of the so-called Mar-a-Lago Accord, which seeks to weaken the dollar’s exchange value while preserving its dominance in global payments. That contradiction sits at the center of his concern.

A major failure could trigger a cross-border financial shock, exposing crypto’s deepest vulnerability, not volatility, but its growing entanglement with legacy power structures.

These risks remain largely theoretical in calm conditions. The real test comes when growth slows, liquidity tightens, and markets begin to strain.

Why It Matters

As the industry moves toward 2026, its direction will depend on which assets can withstand institutional scrutiny and how recession risk, monetary policy shifts, and stablecoin adoption reshape crypto’s place within the dollar-based financial order.

Varoufakis warned that this model outsources monetary power to private issuers, increasing financial concentration while reducing public accountability. The risks, he said, extend beyond the US, as dollar-backed stablecoins spread across foreign economies.

Details

He pointed to his own experience as a case study. O’Leary began as a crypto skeptic, but as regulation started to take shape, he chose to gain exposure.

At first, that meant buying broadly. His portfolio grew to 27 tokens. He later concluded that the approach was excessive. Today, he holds just three cryptocurrencies, which he said are more than enough for his needs.

For O’Leary, each asset serves a specific function. He described Bitcoin as an inflation hedge, often comparing it to digital gold defined by scarcity and decentralization.

Ethereum, by contrast, serves not as a currency but as core infrastructure for a new financial system, with long-term growth tied to its technology. Stablecoins, he noted, were held for flexibility rather than upside.

Dollar Control Moves Onchain

In a BeInCrypto podcast episode, he argued that control over crypto’s monetary infrastructure is tightening, particularly as stablecoins move under closer state and corporate oversight.

Varoufakis pointed to recent US policy as a turning point. By advancing legislation such as the GENIUS Act, Washington is embracing a stablecoin-based extension of the dollar system. Rather than challenging the existing financial order, stablecoins are being positioned to reinforce it.

Looking ahead to 2026, he described stablecoins as a systemic fault line.

Former economic advisor to Ronald Reagan, Steve Hanke, warned that such a stress test is approaching.
