According to Eric Balchunas on Twitter, the KDEF (Korean Defense) ETF has gained 100% since its launch just over four months ago, highlighting substantial momentum in the Korean defense sector (Source: @EricBalchunas, Twitter, June 17, 2025). This performance follows the closure of the KPOP ETF and signals increasing investor appetite for niche, defense-focused funds. For crypto traders, the rapid growth of KDEF underscores a broader risk-on sentiment and potential spillover of capital flows into high-growth sectors, including blockchain and digital assets, particularly those with exposure to security or defense-related projects.
