Craig Erlam, a senior market analyst at London-based consultancy firm, Oanda has said that “darker days” may “still lie ahead” for the cryptocurrency market. Erlam, a former consultant at Goldman Sachs, recently noted in an interview: “Bitcoin appears to have stabilized again following a couple of volatile months that saw it once again come under pressure.” However, Erlam cautioned that bitcoin (BTC), the flagship cryptocurrency, has again started “trading in much tighter ranges” while also continuing to “drift lower.”
