Quantum computing’s threat to Bitcoin has made a Wall Street strategist step away from Bitcoin, insisting the technology is not far away from bringing down the security protocols used by blockchain networks as the world sees. Christopher Wood, the global head of equity strategy at Jefferies, has removed Bitcoins from his model portfolio, ending a position he had once lauded as a hedge against monetary debasement. Wood revealed he sold the coins in the latest edition of his Greed & Fear newsletter, where he said the forward steps quantum computing has taken threaten the foundations of Bitcoin’s investment case.
