I don't think if what goal bitcoin wants but Bitcoin today popular in many countries and use as their legit transaction payments also btc have a high value I think this a good achievement of bitcoin cause btc is only created for fast transactions and no one expect btc will be a powerful coin now.
well, as long as bitcoin is still growing, I feel that bitcoin still has another purpose, and I think the purpose of bitcoin will never run out. well, in general bitcoin will continue to be developed so that it will have new goals continuously.
