I have no doubt in my mind that gold is one of the most important commodity of all time and is also considered as one of best investment since the value is not much affected by the current crisis. If you buy gold coins now, you will surely earn since there value increases overtime.
The only thing that I don’t like about investing in gold is that once that you have sold your gold is that you aren’t going to earn anymore from it. You just got to repeat the process so that you would earn more. This is not the case when it comes to knowledge.
