I'm not sure if satoshi makes bitcoin as an alternative payment system, or with the intention to create the best and most used payment system, but this second option is impossible by the bitcoin nature and i will explain why.
if you are looking for something perfect without any downsides and 0 problems then don't look for it in this universe. what you are seeking is not found anywhere but in an alternate universe!...
lol, maybe you are right, i'm searching perfection in the wrong place. But think about it, it could be perfect if the main focus of the coin where to be the main transactions system. But after read all your comments looks like that wasn't the focus. At end only time can tell us what was satoshi's vision.
