If you see the above chart during the last 30 years, you will see that the ratio gold/silver is almost always between 40 and 80. So, if you were following the chart and sold the gold and bought silver at around 75 and then sold silver and bought gold at around 45, you would have made this operation about 6 or 7 times in 30 years. Today you would have much more silver than you began, without putting new money on it.
