The recent announcement by the Federal Reserve that it's going to keep interest rates low through 2014, strengthens even more the case for gold and silver.
The reason why is it will weaken the dollar, which is always a positive for gold and silver, as it makes it more desirable for investors.
Also, it makes it less expensive and predictable for investors buying on margin to enter the market.
For silver, it has industrial and alternative currence value, which will continue to help it rise as well.
So yes, it is a good time to invest in gold and silver, but you do have to be aware of the cost at your entry point.
