According to the source, Matthew Sigel, Head of Digital Assets Research at VanEck, stated Bitcoin should reach half of gold’s market cap after the next halving, implying a BTC price near $644,000; source: Matthew Sigel of VanEck via X on Oct 7, 2025. Half of gold’s market value is widely estimated in the $7–8 trillion range, framing the implied BTC market cap if this target materializes; source: World Gold Council public estimates of above‑ground gold value. The thesis relies on the halving mechanism that cuts Bitcoin’s block subsidy by 50%, reducing new issuance and serving as a key input in post‑halving supply models used by analysts; source: Bitcoin protocol documentation on block subsidy and halving schedule.

According to AltcoinGordon, VanEck's Matthew Sigel has stated that fiat currencies operate like a Ponzi scheme, positioning Bitcoin as a potential escape for investors. This view highlights a trading opportunity in Bitcoin as a hedge against fiat currency devaluation. Traders should consider the demand for Bitcoin as a refuge asset, which might influence its price dynamics.

According to BitMEX Research, Matthew Sigel appears to have taken an early initiative in an unspecified context, as highlighted in a linked post. This could imply a strategic move or an early adoption in a particular area relevant to cryptocurrency trading.
