VanEck CEO Jan van Eck has indicated that the firm might reduce or exit its Bitcoin holdings if quantum computing advancements compromise current cryptographic security. This statement underscores the potential threat posed by quantum machines to existing encryption methods. VanEck's head of digital-assets research, Matt Sigel, noted the risk of a 'window of uncertainty' should quantum technology reach a level that endangers Bitcoin's cryptographic integrity. The firm highlighted the logistical challenges involved in transitioning Bitcoin to post-quantum signatures, a process that could require up to 76 days of coordinated action. In response to the growing importance of quantum technology, VanEck has also introduced investment products in this field, reflecting its strategic interest in the financial implications of quantum advancements.
