yeah, i think the key thing to keep in mind here is that bitcoin is still in it's infancy.
according to Max Keiser, when bitcoin his $2700 it will be on par with the market capitalization of silver. to this day, silver is still considered a volatile investment. however, that doesn't make it unwise to invest in silver. he further suggests that silver is a good hedge against bitcoin, and that bitcoin investors should peel off 10% and put it into silver.
