my first penny stock purchase.....

so I finally got around to putting some money in my etrade account and I want to try out buying some penny stock.  I was really close to hopping on LEXG before it blew up, but I couldn't pull the trigger because of my lack of experience.  now I thinking of buying like $300.00 of TTIN and hoping that it doubles.  my question is: is it worth it to trade penny stocks for a few hundred dollars, or do you have to invest a few thousand to make any kind of money??
