I really only have one option for investing money and that is gold. There are several ways to do it, but I like to buy different coins the most. You can combine that with collecting. As for where I buy them, here's the website https://www.pacificpreciousmetals.com/product/1039-generic-1oz-gold-round
If you have any questions, there's a blog where you can try to find answers. From myself I also want to add that investing in gold is the most stable.
