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.
So where is it written that the ultimate goal of bitcoin is to achieve global protection? And protection from what? I haven't seen anywhere that bitcoin must be used as the payment method and has to be applied to business transactions. Yeah, it was created to make a trustless payment system without involving third parties.
Unfortunately, at the current state it is almost impossible since there are many problems that needs to be addressed first. Fortunately, various solutions are being forwarded to solve the problems.
