Alright, thanks for the info fellas.

This may sound stupid but am I understanding this correctly in that the mining of bitcoins is actually people doing work on the growing of the block chains' and are rewarded BTC for an amount of work performed.

If that is correct who is the agency responsible for the reward?

Noob question 2:  If you buy 100BTC or 2BTC or 1 BTC would in any of these scenarios you only obtain one private key, or would you receive 100 keys in the first case.
