At this point the amount of money you are talking about is peanuts in the grand scheme of things. If silver goes up by 10% on your $700 investment then you've made a whopping $70. I can spend that much money in one night taking my family to a moderately priced restaurant. And 1% on a CD is even worse.
It's easy to get caught up in the excitement of investing and making money. But until you have some REAL money to invest you are probably just wasting your time. That doesn't mean you shouldn't get educated. But to think that investing say $1000 at 1% is going to do anything at all for your long term financial stability is just wishful thinking.
Don't get discouraged. We've all been there. When I started my first job at 16 years old I already had a passbook savings account with money that I had saved from all of my birthday gifts and chores over the years. This was 28 years ago so the dollar was worth more back then. But my bank account had a whopping $75 in it at the time I got my first job. My very first paycheck for a 20 hour work week was about $50. By the time I had worked 2 measily weeks I had made more money than I had saved in a lifetime. Boy was I bummed.... You might have thought that I'd have been excited. But what I realized is that I had deprived myself of spending that $75 on things that I had wanted all those years. It turned out that the amount of money I had been saving was way too small to make any real difference.
So unless you have several thousand dollars to invest, don't waste your time right now. Enjoy it. Buy whatever you like to buy. Get a girlfriend and take her out for pizza. That's what I did. It also turned out to be the best investment I ever made since I married her and she has a professional career that brings in a 6 figure salary! That thousand dollars I spent dating will turn into several million dollars over my lifetime. How's THAT for a return on your investment?
Not to mention... dating a girl is a HECK of a lot more fun than watching your money grow at 1% in a CD.
