if at this time  i am asked to me out of these two then i will say that only " bitcoin"
because at this time the value of btc is best but also will increase in the next some month .
but if you asked me for 10 year.
then i will tell it is best to store gold for 10 year .
because the value of gold always remain according to average market price but btc may get banned for your country thus .
it would be better to buy gold for 10 year .
