VanEck's Sigel: Quantum Risk Not Yet Big Enough to Sell Bitcoin (BTC)

Sigel: Quantum Not Yet a Sell Signal

Matthew Sigel, who leads digital asset research at VanEck, said on October 3 that quantum computing is not yet a threat large enough to justify selling Bitcoin (BTC), pairing that assessment with a case for the asset to keep expanding its share of investment portfolios over the long term. The distinction he draws is between a risk worth monitoring and a risk worth acting on: the technology belongs on the watchlist, but at its current stage it does not hand a Bitcoin investor a reason to exit a position. The comments carry weight in allocation circles because VanEck sponsors spot ETF products tied to the asset, so the firm's research reaches the same institutional audience its products serve, and the house view on Bitcoin adoption stands unchanged. Sigel argued that Bitcoin's long-term adoption trend remains intact and that reaching a defined portion of the market capitalization of other major investment assets would stand as one of the key reference points in future valuations. He placed Bitcoin alongside gold in the comparison, contending the asset can reach a broader market share within portfolio positions over time. The quantum question has resurfaced repeatedly as researchers sketch hypothetical attacks on the cryptography securing the network's proof of work consensus, and Sigel's answer was direct: the risk is real and long-term, but it currently sits below the threshold that would force holders to sell. In practice, his framing favors investors content to HODL through the noise rather than react to a threat with no working exploit behind it. He attached no date to any possible crossing of that threshold. For desks that treat issuer research as a signal of how allocators are being briefed, the message is that the quantum narrative has not moved VanEck's own stance off its constructive long-term adoption thesis, and his read on the Bitcoin price was framed as structural rather than a near-term call.

AI Demand Lifts Miner Power Assets

The second strand of Sigel's commentary covered an area his desk follows closely: the economics of crypto mining. He said rapid growth in the artificial intelligence sector is making the electrical infrastructure and long-duration energy contracts held by Bitcoin (BTC) mining companies more valuable. In the past, he noted, the fundamental assets of mining companies were assessed mainly through computing power and Bitcoin production capacity. That method, in his view, is starting to change because AI data centers create high and uninterrupted electricity demand that competes for the same grid resources. Some Bitcoin miners, he pointed out, have signed electricity contracts running 10 to 20 years with counterparties that carry investment-grade credit ratings. Those agreements, he argued, give the companies added value not dependent on the asset's market price. As AI expands, inexpensive and stable electricity sources could become scarcer, which raises the strategic weight of long-term energy access. Miners holding that access can convert facilities into infrastructure for AI and high-performance computing, opening new business lines alongside their core operations. The read extends to the market itself: Sigel sees signs that selling-side pressure in the Bitcoin (BTC) market has begun to weaken. That assessment lands during a period when institutional cycle views have been diverging. Dan Gambardello recently abandoned the four-year cycle framework and shifted to a June 2026 bottom call, while Wellington-Altus' Jim Thorne separately pointed to the asset holding its rising 200-week average as a bull case anchor. On-chain fundamentals add texture: the difficulty adjustment at block 969696 eased just 0.03%, a sign of equilibrium between hash power and issuance. Sigel's supply-side argument, that miners now hold two revenue-linked asset bases instead of one, gives that stabilizing market picture a concrete mechanism. Whether AI demand keeps bid support under those contracts is now a variable worth tracking alongside hashrate economics.

Constructive Read, No Stated Trigger

The load-bearing record here is the fund's own research commentary: Sigel, speaking for VanEck, states that quantum computing is a long-term risk to track but not, at the current stage, a level that creates a selling reason for Bitcoin investors. What the remarks do not contain is a boundary. He names no price level, no quantum milestone and no threshold for the weakening sell-side pressure he describes that would flip the house view. Our Bitcoin technical analysis desk reads the position as open-ended: constructive on long-term adoption, unconstrained by any stated trigger. Until such a line is drawn, the 10-to-20-year energy contracts, not the quantum debate, are the part of the thesis with hard numbers attached.
