5K to invest

[dynacraze]

I read somewhere that the worst thing you can do with money is let it stay there b/c you lose because of inflation. Does anyone know whats the best thing to do with 5k? 6 month CD was an option i checked but that will probably make me only 100 dollars though i wished i done that a year ago so I would have made an easy 200 dollars since i haven't touched this money at all.
