not laughing so much buying gold but buying silver at these prices sure could be rewarding if it hits 100 dollars. Im not sure about just how scarce it really is but the industrial demand is very high regardless. Cobalt is something iv been looking into as its going to be needed for batteries in electric cars. Its not an easy thing to invest in and maybe the easiest thing is to get exposure to the miners like Glencore. Id rather own the physical but i dont think its feasible.
