Let me know if that answers your question (:
It sure did 
. To be honest, I knew the difference, but wanted to get this thread started. I'll just ask some stuff that I find interesting to get another opinion, so feel free to ignore my posts if other do actually need help.Ok, next question: There are rumors that Satoshi has ~ 1 mil. BTC. How can we be sure?
We're not sure, it's an estimation. Here's block one. http://blockr.io/block/info/1. For weeks he was testing the system and basically mining alone. If you calculate 50 bitcoins every 10 minutes for the whole period, you can guess how many Bitcoins he and the other early miners have. I'll have to do some more research on the technicalities but I think it's safe to say he has held a ton. One thing we're not sure about is whether or not he still has the private keys for the addresses.
