Yo.
I'm a 16 year old kid and I want to start mining. Right now, I have no GPU and some crappy dual core CPU. I have heard about the Bitforce Jalapenos and I was thinking perhaps they would be best. I'm not in it to make thousands, maybe just for a bit of pocket money- like I hope to make at least $100 a month. Budget on equipment- $500

On a side note, could there be an instance where something terrible happens like some famous BitCoin guy get's arrested and everything is shutdown or the value of bitcoins drop beyond any foreseeable range where it can't pick itself back up?
Any advice would be appreciated!
