As investors we have to be smart, don't just rely on 1 or 2 types of investments, placing money in many types of investments is the best and safest step so that you can get profit, and gold is of course a very good and safe investment because everyone can receive gold.
Gold is easily accessible, easy to liquidate and traditionally a long term investment for any family as an heirloom. Bitcoin is becoming a similar asset too but bitcoin faces the problems from the government about its usage restrictions and "grey-area" labels. This hinders the use of bitcoin as similar as gold has been used.
I am always of the opinion that we should keep each one of every asset balanced in our folio. Be it bitcoin (only one among crypto), precious metals, real estate, stocks, bonds and commodities as far as our knowledge and experience goes. Bitcoin and gold are thus two different assets just like silver and real estate are, hence not comparable but shown to be similar in some aspects.
