yup, gold is still the safest investment. Its value won't degrade through time unlike bitcoin where its value is so volatile. In the future, it is possible that bitcoin won't have any value but gold's price will surely increase as time goes by
Some $5,000,000,000,000 needs to be invested in Gold in a given year so that Gold price goes up +10% that year. So gold is very safe and profits are not more than 20% in a year.
