Can I choose both? The two were not the same and have some advantage and disadvantage. Gold has been there for a long time now and we know how stable it is. Bitcoin price is not stable and we do not know how long will it last on the market. Gold cannot be attain if you have no money to buy for it. Whereas, bitcoin can be earned.
You can choose both. No one can stop you buying 1 BTC and 1 oz of gold the same time if you like and can afford both.
Gold purchases are now quite easy, and the premium is going down. The last time when I purchased a 1g gold coin (1/32 oz.), I paid just 1% premium to the bullion merchant. Compared to that the premium for BTC is slightly higher. In my area, it is not possible to find some seller in Localbitcoins, who is willing to sell coins for less than 3% premium.
