Thanks for sharing your view.
But I am worried about the effects when some bad big event occur in the case of Circle and put Bitcoin (again, like MtGox) in a negative view.
For example, lets assume that Circle will be a huge success. Sounds great right. It is. Now lets assume that the success will be so big that almost everyone will use Circle. When Circle gets too much power turn bad and they decide to destroy primary keys OR will be hacked in some way... When this happens a lot of people lost trust in Bitcoin, because they feel robbed. But this is not Bitcoins fault. It is because people trust to easy on other people. One of the primary goals of Bitcoin is (original Bitcoin document): No one can be trust (and in case you don't trust bitcoin itself, do not use it!). This primary advance will disappear if people decide to store their coins at some place other than by themselves (brainwallet / paper wallet / local pc)

Sorry for my bad English
