Been mining a few months with my PC's GPU and up to 8 coins now. My Jalapeno arrived today so I should be getting coins much quicker. Now that I'm actually starting to get some decent cash, I don't want to lose it.

I'm wondering what is best way to manage the coins. Now the coins I mine I simply have the mining pool send to my account at Mt.Gox. Is that a bad idea? I figure there is a much higher chance of me screwing something up on my end with a bitcoin wallet than Mt.Gox screwing something up.

Appreciate any advice on using a bitcoin wallet vs just keeping coins at an exchange place. Thanks!
