Arthur Hayes and former BitMEX COO Vaidya have teamed up to launch an investment firm called Maelstrom Capital. The firm's objective is to seek returns beyond Bitcoin and Ethereum by focusing on infrastructure companies. They believe that infrastructure is crucial to supporting the exponential user growth currently happening in the market, and their goal is to invest in companies that can meet this demand. Maelstrom Capital, funded primarily by Hayes himself, operates without the constraints of limited partnership agreements or fund allocations, allowing them the flexibility to carefully consider potential investments and patiently wait for promising opportunities.
