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.
Bitcoin achieving a certain goal is too broad. We can already say that it achieved many milestones that is surely hard to surpass by new and old Cryptocurrencies. I still think that Bitcoin has no goal but have a purpose which is to be used in transactions which can result into an easier way of payments. Bitcoin's value is really reassuring and would just entice other people to study and learn it which would also result into another generation of people who would use Cryptocurrency and I guess that might be Bitcoin's goal - For every people to learn about it and use it properly.
