Help!

I really really need some help! I'm just a 16 year old kid, and it's not like I'm going to waste this money, right?

But here is what I AM going to do with it: I want to register a domain (it's a secret, I don't want anyone registering it before me!) and start a brand new, Technology-related blog. Once I'm up and running will this, the use of ads and affiliates promotion should cover the costs. 

It'll be absolutely great if you could chip in, any amount from a few dollars to fifty dollars, any amount would help me a lot! Thanks.
