The measurements of bitcoin success could be through the meaningful uses and achievements. No matter how good and potential bitcoin is if there's no good return to community, country, and citizens bitcoin is just a dream or possible great illusion ever. Nowadays we can see bitcoin as one of the main source of couragement and discouragement through pump and dump scenarios.
We all acknowledge bitcoin as one of the most potential asset among all currencies. Also, most of us witnessed how reliable this asset and strong enough to go beyond a good outcome despite of bearishness. And so, I believe that bitcoin's success can be measured its capability on which can give people's satisfaction and popularity. As long as we keep bitcoin, we can measure success with ourselves.
