Satoshi, in his invention of the blockchain, had given us the inch, what is preventing other bodies or organization from taking the ell? Does it mean no coin hosted on the blockchain will gain mass adoption enough to bypass the users of bitcoin?
The government own billions of population, and by setting her face against bitcoin is a competitor, but doesn't seem to prove that they're a top bitcoin competitor without having a downward course in the process. Last question please forgive me, what stops them from building a coin on the block chain that'll bypass the total sum of bitcoin users, and regulate it?
A little change of perspective, bitcoin is not created for universal acceptance rather it is the acceptance of bitcoin by everyone with it. I see there are many other challenges for bitcoin from the past to the present or in the future, but there doesn't seem to be any convincing.
Instead of a story where we try to express the complexity of the problem, let me describe the great opponent as "the sun", "the atomic bomb", "human cruelty",... It is possible to imagine many other things but perhaps similarly unnecessary to the journey we exist with bitcoin.
