Investing in gold is generally considered to be a hedge against inflation, since gold retains its value while the purchasing power of fiat currencies erodes. However, it becomes less attractive when interest rates rise, as investors don't receive interest or dividend payments for holding gold. That said, gold can be an attractive investment for some investors. If you're wondering if now is the right time to buy gold or if you're considering investing in the future, do some research through a precious metals company.
It can be difficult to receive the full market value of your assets, especially if they are currencies and you need the money quickly. The dollar was produced for several reasons, including the country's large budget and trade deficits and a large increase in the money supply. If gold moves against you, you will be forced to contribute significant sums of money to maintain the contract (called margin) or the broker will close the position and you will suffer losses.
