There's a way but it takes some research and patience. And don't think you'll get rich overnight.
Many people earn decent profits by trading promising alt-coins, but you have to be very careful which coins you choose and when to buy/sell.
Have a look at this thread:

And have a look at this coin for an example:
http://crypto-prices.com/DOGED
People who invested in DOGED early @ 1 satoshi price are now selling it @ 5 satoshi, earning 4x profit.
I'm not telling you to invest in DOGED, I'm just saying if you make careful decisions, alt-coin trading can surprise you.
