In my opinion, bitcoin has not reached its goal. I know that this bitcoin developer wants bitcoin to be the number one legitimate currency used worldwide such as dollars. Now, bitcoin is ranked 6th to compete with other fiat currencies such as dollars and euros. Bitcoin is very ambitious to be the number one currency but bitcoin hasn't gotten legal status from all countries in the world. This is of course a sign that the purpose of bitcoin has not been achieved because bitcoin still has many challenges to realize its dream. Beating the dollar and euro is not easy because both currencies are rooted in the use of people around the world.
