Arthur Hayes, co-founder of BitMEX, announced that his family investment office, Maelstrom, is actively purchasing high-quality altcoins. This move comes as Hayes continues to express confidence in the cryptocurrency market, particularly in light of macroeconomic factors. Previously, Hayes highlighted the Bank of Japan's policy of maintaining negative real interest rates, suggesting it could drive Bitcoin's value into the millions. His latest investment strategy reflects a broader optimism about the potential for significant gains in the altcoin sector.
