State Street Global Advisors' strategist George Milling-Stanley cautioned that the recent bitcoin rally could mislead investors into feeling overly secure about their investments. Comparatively, he highlighted gold's stability and reliability, emphasizing that bitcoin, being primarily a return play, lacks the protective qualities of gold. Milling-Stanley's insights came during a period when the SPDR Gold Shares ETF, the world's largest physically backed gold ETF, marked its 20-year anniversary with significant historical growth. Meanwhile, bitcoin has seen considerable gains, reaching new highs post the November elections.
