Look around and jump on the BitShares exchange. I'm sure you can find a couple coins with promising futures, which you can pick up for a few pennies each. ;)
Let folks know you're buying dodge coins or something else with a low fee. Buy them $5 at a time and send them to your BitShares account. Put in some low bids for a few different coins, buy some every month. $5 can go a LONG way with almost any new coin. It only takes one penny coin, shooting to $10 and your 500 coins are worth $5,000. ;)
Be Smart, do your research and invest in coins with a purpose, a solid development team (with track record) and a great marketing department. :)
