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 was created to solve some problems connected with the fact that governments have a complete control over finances and can release as much money as they want disregarding inflation. Also Bitcoin was made to exclude an intermediary between the one who pays and the one who receives the payment. These two functions, Bitcoin is capable of performing, but it is still not so widely used.
