Dear BitCoin Community,


Iam very new to this whole thing.
I like the whole idea and even am mining a bit with my old pc.
I get the whole system except one thing..

Where does the money come from when mining?
Who pays for these useless calculations?
I mean at the end you simply get money from a other person when mining right?
Or is this simply money for free?  (if we don't look at the electricity bills ofcourse)

EDIT: Some other question just raise up into my mind.
Can Bitcoin collapse if 95% of all people suddenly leave cause Google made a announcement of some kind?

Thats all for now.


Thanks in advance.
