Bitcoin has accomplished a lot over the last few years and deserves a lot of credit for it but has not achieved its goal yet. Bitcoin is set to achieve global protection whereby everyone will accept its use in terms of payment methods and apply it to their business and transactions.
based on the data I read on a news some time ago, currently bitcoin users are less than 2% of the world's population...
bitcoin is still too young so it can't be said that it has fully achieved its goal created by satoshi, but the best thing right now is that bitcoin will not be destroyed at any time and will continue to exist in this world.
Satoshi did not create Bitcoin so that everyone could use Bitcoin, He actually wanted to make a payment system that is independent, no one has the power to control or alter the transactions in Bitcoin that conventional Banks can do.
From, Satoshi's perspective, it truly gained its success. many hackers tried to hack Bitcoins, but they failed. many technicians wanted to crack private keys but they are extremely failed. The government wanted to regulate the Bitcoin system but they also failed badly, the government tried to ban Bitcoin but they failed to prevent people to use Bitcoin. Bitcoin is a unique system, no one can take over it.
