" What has been the development of Bitcoin and improvement since that statement was made till now?
And will Bitcoin (satoshi dream or goal ) be fully accepted in the world as a means of payment?.
The work hasn't been done and will never be. Right now, bitcoin is in its very early stage. There are a lot of space to improve over here and people all together are still contributing. As for the "never will be" part, it is true. It will keep on improving as long as the environment, technologic, people, economics and so on keeps on changing. Do you think "technology" has a final form/stage?
Bitcoin? Maybe not. Some centralized cryptocurrency, maybe.
