Digital currencies are an unfounded fad: Billionaire Marks
Investment firm Oaktree Capital's Co-chairman Howard Marks said, "[D]igital currencies are nothing but an unfounded fad (or perhaps even a pyramid scheme)." This is "based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", he added. Notably, Bitcoin has risen 900% in the last two years against the dollar.
